A large mall is built in the shape of a square. At each corner of the mall stands a pillar which is topped by a pyramid-shaped section of red tin roof, as shown in the picture below.



The pyramid is a square pyramid, measuring 21.5 feet on each of its base edges. The height of each of the triangular lateral face is 13.4 feet.

How many square feet of red tin roof does each pillar contain? [Type your answer as a number. Do not round.]

a0 square feet

Answer 1

Answer:

576.2

Step-by-step explanation:

The formula for the area of a triangle is $\frac{bh}{2}$. Since this square pyramid is essentially four triangles with base length 21.5 feet and height 13.4 feet, we can calculate the area that they take up with the formula $4\cdot \frac{13.4\cdot 21.5}{2}=576.2$ square feet. Hope this helps!
