Question

You have a square pyramaid the area of the square is 25 cm and the slant height of the pyramaid is 10 find the total surface area of the pyramaid

Answer 1

125cm^2

Explanation:

the area of a triangle is b*h/2 and area of a square is side*side so since the area of the square is 25 the side length must be 5 because 5*5=25

that being said we use 5 as base for the triangles and 10 as height

area of a triangle= 5*10/2=25 since there are 4 triangles 25*4=100cm^2 +square base (25 cm^2)=125cm^2
