Question 791681: A rectangle’s length is 2 centimeters more than its width. The area of the rectangle is 63 square centimeters. Find the dimensions of the rectangle

Width = x
Length = 2 + x
Area = Width * Length
63 = x * (2 + x)
63 = 2x + x^2
x^2 + 2x - 63 = 0
(x + 9)(x - 7) = 0
x + 9 = 0
x = -9 No answer as x < 0
x - 7 = 0
x = 7
Width = 7cm
Length = 9cm.
Hope this helps.
