Answer:
<h2>Trenton needs 21 square feet of plywood to cover all the surface of the ramp.</h2>
Step-by-step explanation:
Givens
- Base is 2 feet long.
- Height is 1.5 feet long.
- Length is 3 feet long.
- The riding surface is 2.5 feet long.
Notice that the ramp is formed by two triangles and three rectangles.
Each triangle has a base of 2 feet and a height of 1.5 feet. So, the area of each triangle is
The base of the ramp has dimensions of 3 feet x 2 feet. Its are is
The back of the ram has an area of
The riding surface is
So, basically, to know the total surface, we just have to sum the are of both triangles, and the area of all three rectangles, as follows
This means that Trenton needs 21 square feet of plywood to cover all the surface of the ramp.
