QUICK QUICK PLZZ! ANSWER QUESTION ONLY 1 MINUTE ONLY WITH SOLUTION! THE YOU WILL BE THE BRAINLIEST
nekit [7.7K]

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!
