Question

What is the surface area?

Answer 1

10.2 ft^2

Explanation:

The formula for the surface area of a pyramid is:

`SA=B+(1)/(2)l(numberofbasesides)(b)`

B will be the area of the base, which is the triangle. After we figure out the value of B we can plug everything we know into the equation.

The formula for the area of a triangle is:

`A=(1)/(2)bh`

`A=.5*2*1.7`

A = 1.7

Now that we have the value of B, we can plug it into the formula along with the other things from the picture we know.

`SA=1.7+.5*2*3*2`

`SA=`

10.2 ft^2
