The base of a triangle is 18in. The height is 10in. What is the area of the triangle?

90in²

Step-by-step explanation:

Area of a triangle, A = 1/2 x base x height

We are given, base = 18in

Height = 10in

Therefore, A = 1/2 x 18in x 10in

= 90in²

The area of the triangle with base 18in and height 10in is 90in²
