Let
w=width, then
length = 2w+5 m
Area = 88 m²
w(2w+5)=88
2w²+5w-88=0 ...(1)
Solve for w in equation (1) by factorization or otherwise and reject the negative root.
the length of a rectangle is 5m more than twice its width. and the area of the rectangle is 88m^2. find the dimensions of the rectangle.
