Answer:
936 cm^2
Explanation:
Solution
Back (This is a rectangle)
Area = w * h
w = 7
h = 18
Area = 7 * 18 = 126 cm^2
Front and Back
Area = 1/2 * B * H (This is a triangle -- There are 2 of them)
Givens
B = 24
h = 18
Area = 1/2 * 24 * 18
Area = 216
But there are two such triangles = 2*216 = 432 cm ^2
Ramp
Formula Area = L*w (This is a rectangle)
L = 30
W = 7
Area = 30 * 7 = 210 cm^2
Base
This is also a rectangle
L = 24
W = 7
Area = L*W
Area = 24 *7 = 168 cm^2
Total
168 cm^2
210 cm^2
432 cm^2
126 cm^2
936 cm^2
