Answer:

Hello it has been a long time since I did this.  

The formula is bxhx1/2=

18x10x1/2

180x1/2

90

* If it is easier you can just do divide by 2*

Answer:

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
