Step 1) Find the area of the faces

There are 4 triangular faces on this rectangular pyramid. In this case, they are all the same, because each triangle has the same base and height. We will find the area of 1 triangle and multiply it by 4 to find the area of all of the triangular faces.

A = 1/2 x 3 x 2

A = 1/2 x 6

A = 3

3 x 4 = 12

A = 12 cm^2

Step 2) Find the area of the base

The base has a length of 2 cm and a width of 2 cm. We can find the area of the base by multiplying the length and width because the base is a rectangle.

A = 2 x 2

A = 4 cm^2

Step 3) Add the areas together

Now, we need to add the area of the faces and the area of the base together to find the surface area.

A = 12 + 4

A = 16 square centimeters

Hope this helps! :)
