Consider the right triangle below

vaieri [72.5K]

Answer:

6.5

Step-by-step explanation:

Hi Davion2525!

I'd believe you are asking for the area of the triangle.

In that case, we are solving 6 · 2.5

(Formula = $\frac{1}{2}$ B · H)

$\frac{1}{2}$ · 6 = 3

3 · 2.5 = 6.5.

Thus, the answer is $\boxed{6.5}$ ft²
