Question

The legs of a right triangle measure

18 inches and 12 inches. What is the area
of the triangle?

Answer 1

108 in²

Explanation:

Given that the legs of a right triangle are 12" and 18".

Be cause it is a right triangle (with 90 degrees between the legs), we can arbitrarily assign one of these to be the height and the other value automatically becomes the base.

Let 12" be height and 18" be base

area = 1/2 x height x base

= 1/2 x 12 x 18

= 108 in²
