Answer:
A = 110.9 ft²
Step-by-step explanation:
Assuming that the triangle is equilateral, all of the sides are 16 ft. You also have to find the height of the triangle to find the area. Use Pythagorean Theorem to find the height.
a² + 8² = 16² Simplify
a² + 64 = 256
- 64 - 64 Subtract
a² = 192 Take the square root of both sides
a = √192
Now you can solve for the area using the following equation.
A = [tex]\frac{1}{2}[/tex]bh Substitute
A = [tex]\frac{1}{2}[/tex](16)(√192) Multiply
A = 8(√192) Multiply
A = 110.9 ft²
