First, regard the figure Regardng the figure as one large rectargle, the algebraic expression for the avea as one large rectangle, and then regard the figure as a sum of four smaller rectangles of the figure is (Simplify your answer) Regarding the figure as a sum of four smaller rectangles, the algebraic expression for the area of the figure is (Simplity your answer) Enter your answer in each of the answer boxes

Explanation / Answer

area of one large rectangle is

length = y + 7

width = y + 7

algebraic expression for 1 large rectangle is

area = (y+7)^2

area of 4 small rectangles

area 1 = y*y= y^2

area 2 = 7*y = 7y

area 3 = 7y

area 4 = 7*7 = 49

algebraic expression for area of 4 small rectangles = y^2 + 7y+7y + 49

= y^2 + 14y + 49
