Question

I need to know the formula and how to get to the answer ASAP

Answer 1

Explanation:

The formula for the area of this triangle is

`A=(1)/(2)bh`

Since we have a value for area, and we know that both the base and the height are x, then the formula can be rewritten as

`27=(1)/(2)x^2`

Multiply both sides by 2 to get rid of the fraction to get

`54=x^2`

Undo the square on the x by taking the square root of both sides. Rounding to the neareast tenth gives you that x = 7.3
