Question

I SPENT 50 POINTS ON THIS, PLEASE HELP

The formula for the area of a triangle is A=1/2bh where b is the base and h is the height. what is the area of the triangle shown here? (see picture)
a. 72 in^2
b. 90 in^2
c. 180 in^2
d. 360 in^2

Answer 1

In the figure, we can consider that the base is the side that measures 12 in and that the height is the side that measures 15 in, since that sides are perpendicular. So, we just need to use the given formula

so it =d

Explanation:

Answer 2

In the figure, we can consider that the base is the side that mesures 12 in and that the height is the side that measures 15 in, since that sides are perpendicular. So, we just need to use the given formula:

`A = (bh)/(2)\Longrightarrow A = (12\cdot15)/(2)\Longrightarrow A=6\cdot15\Longrightarrow \boxed{A = 90~\text{in}^2}`

Hence, the area of the triangle is 90 in² (B).
