How do we find the lateral area of this rectangular pyramid?

• Find the area of each lateral side using 1/2 x base x height since they are triangles, then multiply each area by 4 since there are 4 lateral sides.

• Find the area of each lateral side using length times width since the lateral side is a rectangle, then multiply each area by 4 since there are 4 lateral sides.

• Find the area of the lateral side using base x height since it is a rectangle.

• 7 x 4 x 4 ÷ 2
