Step 1:

Step 2:

Step 3:

Step 4: *

(20 Points)

Step-by-step explanation:

Step 1:   Set up the formula for the surface area of a regular pyramid.

SA =

where :

Step 2:  Plug the perimeter of the base into the formula

you can calculate the perimeter by multiplying the length of one edge by the number of edges.

Step 3: plug the value of the slant height into the formula (it is not the perpendicular height)

Step 4: find the area of the base (depend on the shape of the base)

Hope it will find you well.

4th option is correct xy=-10
