A diagram of Miles’ skateboard is shown below with its dimensions. If Miles plans to paint the ramp, excluding the bottom, what is the area in which he will paint?

Question

Is the answer 1867.2? A of triangle is 1/2 (41.8) (24) = 501.6. A of rectangle is 24 (36) = 864. 2(501.6) + 864 = 1867.2

Answer 1

Yes that is the correct answer.

You have two triangles that are 41.8 by 24, where area of each is 1/2 * 41.8 * 24 = 501.6. So both = 1003.2.

You have one rectangle that is 24 by 36, so area is 864

Total area is 1003.2 + 864 = 1867.2
