Question

What is the surface area?

Answer 1

10.2 ft^2

Step-by-step explanation:

The formula for the surface area of a pyramid is:

$SA=B+\frac{1}{2}l(numberofbasesides)(b)$

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:

$A=\frac{1}{2}bh$

$A=.5*2*1.7$

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
