Question

Whats the area of this triangle ​

Answer 1

`\large\boxed{A=16\sqrt3\ in^2\approx27.7\ in^2}`

Explanation:

It's the equilateral triangle.

The formula of an equilateral triangle wit sides a

`A=(a^2\sqrt3)/(4)`

We have a = 8in. Substitute:

`A=(8^2\sqrt3)/(4)=(64\sqrt3)/(4)=16\sqrt3\ in^2`

Answer 2

(8÷2)^2+x^2=8^2
16+x^2=64
x^2=48
x=√48

(8×√48)÷2=27.71...

Answer:27.7in^2
