the length of a rectangle is 3 feet less than 5 times its width. the perimeter is 78 feet. find the length and width of the rectangle

Answer provided by our tutors

Let 'l' and 'w' stand fro the length and wide of the rectangle. We can write:


l=5w-3

2l+2w=78


Using Algebrator to solve for l and w, we get:

l=32 feet

w=7 feet
