Answer 1

C

Explanation:

got it on edge

Answer 2

Answer: The width is 12 feet shorter than the length.

Explanation:

The area of a rectangle can be calculated with this formula:

`A=lw`

Where "l" is the lenght and "w" is the width of the rectangle.

We know that lenght of Jennie's yard is 30 feet, the width is
`(30-x)ft` and the area is 540 square feet. Then:

`l=30\\w=(30-x)\\A=540`

Substitute these values into the formula and then solve for "x":

`A=lw\\\\540=30(30-x)\\\\540=900-30x\\\\30x=900-540\\\\x=(360)/(30)\\\\x=12`

Therefore, the width is 12 feet shorter than the length.
