Me by marking the correct answer to each part of number 9. i really dont get this at all, so tell me why your answer is correct (step by step) plss tell me how and why this is your !

9a) False, The dimensions are 10 x 20

b) True, 10 x 20 = 200

c) 10-6=4   (right side minus left side)
    26-20=6 (bottom line minus top line)

d) True, Area of a triangle = (base x height) / 2

The base is 6 and the height is 4, so 6 x 4= 24 / 2 =12

e) True, the total area is equal to the triangle area plus the rectangles area.

so, 200+12= 212
