Question

you install 618 feet of fencing along the perimeter of a rectangular yard. The width of the yard is 152 feet. What is the length of the yard?

Answer 1

The length of the yard is 157 feet

Explanation:

P= L+L+W+W or 2L+2W. (P is perimeter, L is length, and W is width.)

Substitute in known values for the variables.

618=2L+2(152)

Multiply.

618=2L+304

Now solve for L by doing inverse operations (subtract).

314=2L

Divide.

L=157

So the yard is 157 feet long.
