Introduction

In this article, we will explore the concept of finding the height of a rectangular poster given its area and width. We will use mathematical formulas and calculations to determine the height of the poster.

Understanding the Problem

A rectangular poster has an area of 26 square feet. The width of the poster at its base is $$4 \frac{1}{3}$$ feet. We need to find the height of the poster.

The Formula for Area

The formula for the area of a rectangle is:

Area = Length × Width

In this case, the area is 26 square feet, and the width is $$4 \frac{1}{3}$$ feet. We need to find the length (or height) of the poster.

Converting the Width to an Improper Fraction

To make calculations easier, we will convert the width from a mixed number to an improper fraction.

4 \frac{1}{3} = \frac{(4 \times 3) + 1}{3} = \frac{12 + 1}{3} = \frac{13}{3}

Substituting the Values into the Formula

Now that we have the width in improper fraction form, we can substitute the values into the formula for area:

26 = Length × $$\frac{13}{3}$$

Solving for the Length

To find the length, we will divide both sides of the equation by $$\frac{13}{3}$$:

Length = $$\frac{26}{\frac{13}{3}}$$

To divide by a fraction, we will multiply by its reciprocal:

Length = 26 × $$\frac{3}{13}$$

Length = $$\frac{26 \times 3}{13}$$

Length = $$\frac{78}{13}$$

Length = 6

Conclusion

The height of the rectangular poster is 6 feet.

Introduction

In our previous article, we explored the concept of finding the height of a rectangular poster given its area and width. We used mathematical formulas and calculations to determine the height of the poster. In this article, we will answer some frequently asked questions related to finding the height of a rectangular poster.

Q&A

Q: What is the formula for finding the height of a rectangular poster?

A: The formula for finding the height of a rectangular poster is:

Height = $$\frac{Area}{Width}$$

Q: How do I convert a mixed number to an improper fraction?

A: To convert a mixed number to an improper fraction, follow these steps:

Multiply the whole number part by the denominator.
Add the product to the numerator.
Write the result as an improper fraction.

For example, to convert $$4 \frac{1}{3}$$ to an improper fraction:

Multiply 4 by 3: 4 × 3 = 12
Add 12 to 1: 12 + 1 = 13
Write the result as an improper fraction: $$\frac{13}{3}$$

Q: What if the width is not given in feet? How do I convert it to feet?

A: To convert the width from another unit to feet, you need to know the conversion factor. For example, if the width is given in inches, you can convert it to feet by dividing by 12 (since there are 12 inches in 1 foot).

Q: Can I use the formula for area to find the height of a rectangular poster?

A: Yes, you can use the formula for area to find the height of a rectangular poster. The formula for area is:

Area = Length × Width

To find the height, you can rearrange the formula to:

Height = $$\frac{Area}{Width}$$

Q: What if the area is not given in square feet? How do I convert it to square feet?

A: To convert the area from another unit to square feet, you need to know the conversion factor. For example, if the area is given in square inches, you can convert it to square feet by dividing by 144 (since there are 144 square inches in 1 square foot).

Q: Can I use a calculator to find the height of a rectangular poster?

A: Yes, you can use a calculator to find the height of a rectangular poster. Simply enter the values for area and width, and the calculator will give you the height.

Tips and Tricks

Always convert mixed numbers and improper fractions to a common form to make calculations easier.
Use the formula for area to find the height of a rectangular poster.
Convert the width and area to the same unit (e.g., feet) to make calculations easier.
Use a calculator to check your calculations and ensure accuracy.

Conclusion

In conclusion, finding the height of a rectangular poster is a simple yet important mathematical concept. By understanding how to apply the formula for area and convert mixed numbers and improper fractions, we can solve problems and apply mathematical concepts to real-world situations. We hope this Q&A article has helped you understand the concept better and has provided you with the tools and tips you need to find the height of a rectangular poster.
