Find the area of this figure

90ft²

Step-by-step explanation:

Figure shown is a triangle

Area of a triangle = ( base length times height ) divided by 2

The triangle has a given height of 12 ft and a given base length of 15 ft

Hence area = ( 12 * 15 ) / 2

12 * 15 = 180

180 / 2 = 90

area = 90ft²

Area is 90 degrees.

Step-by-step explanation:

The formula for the area of a triangle is (h*b)/2=A

We know height is 12.

We know base is 15.

So lets plug these in:

(12*15)/2=A

180/2=A

90=A

So 90 is our answer!
