Question

The diagram below represents the measurements of Jennie’s yard. The yard’s width is x feet shorter than its length. If the area of the yard is 540 square feet, how many feet shorter than the length is the width? A yard with a length of 30 feet and a width of (30 minus x) feet. Solve the equation to find how many feet shorter than the length the width is. 30(30 – x) = 540 What is the value for x?

Answer 1

Solve the equation to find how many feet shorter than the length the width is.

30(30 – x) = 540

What is the value for x?

✔ 12

Answer 2

X=12

Explanation:

1. Divide both sides by 30: 30(30 – x) = 540/30 = 540/30

2. Simplify: 30-x=18

3. Subtract 30 from both sides: 30-x-30 = 18-30

4. Simplify: -x = -12

5. Divide both sides by -1: -x/-1 = -12/-1

6. Simplify: x=12
