# Thread: Surface area of a pyramid

1. ## Surface area of a pyramid

Hello Guys vaironxxrd here with a though problem for me again .... I can't seem to know how to find the Area of the Base.

2. If the base was square (how do we know?) then

$4 \times 11.2$

would be the perimeter, not the area.

3. because 11.2 is not the Apothem?
