Look at the triangle below:
If you multiply the base by the perpendicular height, you get the area of a rectangle. The area of the triangle is half the area of the rectangle.
So, to find the area of a triangle, multiply the base by the perpendicular height and divide by two. The formula is:
Remember to only use the perpendicular height of the triangle in place of .
Find the area of this triangle:
The area of the triangle is:
