144 squared ft
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
Given the information:
- height - 3
- length - 11
- width - 4
- slant height - 5
As we know that, the ramp is a triangular Prism, so to find how much wood did it take to cover the ramp we need to find the total surface area of the triangular prism
1/ The area of the central rectangle
A = lw = 11*4 = 44 squared ft
2/ The area of the rectangle to the left
A = hw = 3*4 =12 squared ft
3/ The area of the rectangle to the right
A = slant height* length = 5*11 = 55 squared ft
4/ The area of the two triangles
A = 2 (1/2*h*l) = h*w = 3*11 = 33 squared ft
=> the total surface area of the ramp is: 44 + 12 + 55 + 33 = 144 squared ft
Hope it will find you well.
