Answer 2

Answer:

519.04ft^2

Step-by-step explanation:

a=30 b=36 c=40

Using the formulas:

A=$\sqrt{s(s-a)(s-b)(s-c)$

s= a+b+c /2

Solving for A:

A= $\frac{1}{4}$$\sqrt{-ax^4+2(ab)^22(ac)2-b^4+2(bc)^2-c^4 }$

=$\frac{1}{4}$$\sqrt{-30^4+2·(30·36)^2+2·(30·40)^2-36^4+2·(36·40)^2-40^4}$

≈519.03661ft²
