Ella and Jake love to skateboard. They created a frame for the ramp and then covered it with wood.

How much wood did it take to cover the ramp, including the bottom?

Answer:

Explanation:

  • Two triangular ends
  • Area of one = 1/2 b * h
  • b =1.2
  • h =0.9
  • Area = 1/2 * 1.2 * 0.9 = 0.54 sq meters
  • Area of 2 = 2 * 0.54 1.08

Area bottom

  • L = 3.5 m
  • w = 1.2
  • Area = L * W
  • Area = 3.5 * 1.2
  • Area = 4.2

Area Back

  • L = 3.5
  • W = 0.9
  • Area = 3.5 * 0.9
  • Area = 3.15

Area Slanted piece

  • L = 3.5
  • w = 1.5
  • Area = L * W
  • Area = 3.5 * 1.5 = 5.25

Total = 5.25 + 3.15 + 4.2 + 1.08 = 13.68
