Question

The perimeter of a rectangle is 60 feet. the length is 2 feet more than 3 times the width. find the width of the rectangle

Answer 1

2w+2l=60 and l = 3w+2

All we need to do to find width is substitute the length in the perimeter formula with the length formula we have established.

2w+2(3w+2)=60
2w+6w+4=60
8w+4=60
8w=56
w=7

width is 7 feet
