Question

A restaurant is building a ramp to make the facility more accessible to people in wheelchairs. They covered the entire surface of the ramp with metal to make it more durable. How much metal did they use to cover the ramp, including the bottom?
Please find the Surface Area.

Answer 1

Answer:

$1.79\ m^{2}$

Step-by-step explanation:

we know that

The surface area of the triangular prism is equal to

$SA=2B+PL$

where

B is the area of the triangular base

P is the perimeter of the triangular base

L is the length of the prism

Find the area of the triangular base B

$B=\frac{1}{2}(0.8)(0.1)=0.04\ m^{2}$

Find the perimeter of the triangular base P

$P=(0.8+0.1+0.81)=1.71\ m$

we have

$L=1\ m$

substitute the values and find the surface area

$SA=2(0.04)+(1.71)*(1)=1.79\ m^{2}$
