Question

Julie's yard is rectangular. One side of the yard is 100 feet wide. The total area of the yard is 3,000 square feet. What is the length of the other side of the yard?​

Answer 1

Explanation:

Let's call the length of the yard "L" (in feet).

We know that the width of the yard (W) is 100 feet, and the area of the yard (A) is 3,000 square feet.

The formula for the area of a rectangle is:

A = L x W

So we can plug in the values we know:

3,000 = L x 100

To solve for L, we can divide both sides by 100:

3,000 ÷ 100 = L

30 = L

Therefore, the length of the yard is 30 feet.

Answer 2

Explanation:

Let's assume the length of the yard is "x" feet. We know that the total area of the yard is 3,000 square feet, so we can write:

Area = Length × Width

3000 = x × 100

Divide both sides by 100:

30 = x

Therefore, the length of the yard is 30 feet.
