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:
Area = (b × h)/2
Find the area of this triangle:
The area of the triangle is:
(5 × 8)/2 = 40/2 = 20cm2
