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*
90in²
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
