## OMG

Iduj wears a very funny hat in the shape of a triangle OMG. The altitude from point M is drawn to point A on side OG. If OM is 13 inches, MG is 20 inches, and GA is 16 inches, find the area, in inches squared, of Iduj’s triangular hat.

*Hints or steps on how to get the answer is appreciated.*

Hello, Nadeshiko!

Did you make a sketch?

Iduj wears a very funny hat in the shape of a triangle OMG.

The altitude from point M is drawn to point A on side OG.

If OM is 13 inches, MG is 20 inches, and GA is 16 inches,

find the area, in inches squared, of Iduj’s triangular hat.

Code:M * *| * * | * 13 * | * 20 * | * * | * * | * * | * O * * * * * * * * * * * * * G A 16

. . Hence: .

In

. . Hence: .

Therefore, triangle has:

. . base

. . height

Got it?

You could also "cheap out" and use Heron's formula.
