Question

The length of a rectangle is 8 more than the width. the area is 180180 square feet. find the length and width of the rectangle.

Answer 1

8l = w

area = 180180

area = lw

180180 = lw
since w = 8l as shown above 
180180 = (l)(8l)
180180 = 8l^2
l^2 = 22522.5
take the square root 
l = 150.075 to three decimal places

180180 = lw
we now know that l = 150.075
180180 = (150.075)(w)
w = 180180/150.075
w = 1200.5997

width = 1200.5997
lentgh = 150.075
