1. Vocaloid

start by finding the area of the base

2. annmeez

i have the area of the rectangular prism

3. happy_to_help

$A=a^{2}+2a \sqrt{\frac{ a^{2} }{ 4 }}+h^{2}$ Use this formula A=Base edge H=Height

The pyramid is a right square pyramid. That means the base is a square. We are shown that all edges of the base measure 5.3 yd. That means you can find the area of the base using the formula for the area of a square. Now you need to find the areas of the 4 triangular sides. All sides are congruent, so you need to find the area of one triangular side, and multiply that area by 4. Each side is a triangle with base 5.3 yd and height 11.1 yd. Use the formula for the area of a triangle with those measures for the base and height, and find the area of one side. Then multiply the area of one side by 4 and add to the area of the square base.
