Question

Jay wants to make a bike ramp a draw the following sketch what is the surface area of the ramp

Answer 1

We find the surface area of the figure by dividing the figure into smaller ones. This is:

Area 1, rectangle:

`A=\text{length}* width=2.2*1.6=3.52`

Area 2, triangle:

`A=(base* height)/(2)=(2*0.9)/(2)=0.9`

Area 3, rectangle:

`A=1.6*0.9=1.44`

Area 4, triangle:

`A=(2*0.9)/(2)=0.9`

Area 5, rectangle:

`A=2*1.6=3.2`

Therefore, the surface area of the ramp is:

`A=A1+A2+A3+A4+A5`

Substitute the corresponding values:

`A=3.52+0.9+1.44+0.9+3.2=9.96`

Answer: 9.96 m^2
