Question

You install 538 feet of fencing along the perimeter of a rectangular yard. The width of the yard is 127 feet. What is the length of the yard?

Answer 1

so, you know that perimeter is equal to 2 times width + 2 times length. if the width is 127, then you must multiply it 2 times getting 254, then you’re gonna subtract than number from 538, getting 284 (that’s 2 times length) so simply divide by two to get the answer.

answer: 142feet
