The length of a rectangle is (x+2) inches. The width of the rectangle is (x+1) inches.

Question

Write an equation that can be used to determine the area (A) of the rectangle in terms of x.

What is the value of x if the area of the rectangle is 56 square inches?

Answer 1

(x+1)(x+2) = A
x^2 + 3 x + 2 = A

x^2 + 3 x + 2 = 56

x^2 + 3 x - 54 = 0

(x+9)(x-6) = 0

x = 6

Answer 2

this is very stupid
