Question

The width of a rectangle is 4 units more than the length. If the area is 60 square units, then find the dimensions of the rectangle

Answer 1

w = L + 4

Area = L * W = L"(L+4)

60 = l^2 + 4l

0 = L^2 + 4L - 60

0 = ( L + 10 )( L - 6 )

L+10 = 0 results in negative measures

L - 6 =0 --> L = 6

rectangle 6 by 10
