Problema Solution
A rectangle is 5 times as long as it is wide. The area is 180 square feet. What is the perimeter of the rectangle?
Answer provided by our tutors
Let 'l' and 'w' stand for length and width of the rectangle. We can write:
5w=l
lw=180
Solving for 'l' and 'w', we get:
l=30 ft
w=6 ft
Therefore the perimeter is:
perimeter=2l+2w= 2(30)+2(6)=72 ft
