A rectangle is drawn so that the width is 4 feet shorter than the length. The area of the rectangle is
60 square feet. Find the length of the rectangle.

the length of the rectangle is 10ft

Step-by-step explanation:

let the length = x

width = x - 4

area = length X width

so, according to the problem

x(x-4) = 60

or, - 4x = 60

or, -4x -60 = 0

or, - 10x + 6x -60 = 0

or, x(x-10) +6(x-10) =0

or, (x-10)(x+6) = 0

x = 10 ( x= -6 for length this value is not possible)

so length is 10ft

width = 10 - 4 = 6ft
