Answer:

972 m²

Explanation:

first area(square base)= 18²=324

all four triangles have the same area

area(triangle)= (1/2)(base)(height)

(1/2)(18)(18)=162

times 4 triangles

4(162)=648

add square base

=972

The answer is 972 m^2
This is because there are 4 triangles (18*18/2) + one square (18*18) = 972
