Solve the problem.Find the area of the large rectangle below in two ways. First, find the sum of the areas of the four smaller rectangles. Second, express the area of the large rectangle as the product of its length and width. 
A. area = x2 + 3x - 2 = (x + 2)(x - 1)
B. area = x2 + 4x - 3 = (x + 3)(x - 1)
C. area = x2 + 4x + 3 = (x + 3)(x + 1)
D. area = x2 + 3x + 2 = (x + 2)(x + 1)
