A room has 2 sections as shown in the picture below. Which expression uses the Distributive Property to find the total area of the room?
(A rectangle is divided into two smaller rectangles by a vertical line. The vertical height of the rectangles is 14. To the left, the larger of the two smaller rectangles has a width of 8. To the right, the smaller of the two rectangles has a width of 4.)
A.14 + (8 × 4)
B.14 × (8 + 4)
C.14 × 8 x 4(My answer)
D.14 × 8 × 14 × 4
look the area of the big one is 14*8
and the area of the little one is 14*4
total area = 14*8 + 14*4
NOW what does distributive property say?
a*b + a*c = a * (b+c)
and you could always check it because from the start when you DREW the RECTANGLE you knew
area = 14*12
