Lateral Area=Perimeter of the base * height perimeter=20 height=6 so, Lateral Area=20 * 6 Lateral Area=120cm
False
Pyramid (regular) Lateral area : pl/2, where l = slant height : p = base perimeter Total area : pl/2+B where B = Base area.

Find the surface area of each individual face and then add them together to give the total surface area of the pyramid.
The surface area is the area of the base plus the area of the slanted sides:SA = ba + lala = ps→SA = ba + ps
False

Yes.
An isosceles trapezium.
