Area = 90 units^2

Step-by-step explanation:

For the area of a triangle, we can simply use the following equation:

Area = ( 1 / 2 ) * Base * Height

We are given a base of 12 and a height of 15, so we can simply plug those values into the formula to find the area.

Area = ( 1 / 2 ) * Base * Height

Area = ( 1 / 2 ) * 12 * 15

Area = 6 * 15

Area = 90

Hence, the area of our triangle is 90 units^2.
