A triangle is always half the area of a rectangle with the same height and width.

To calculate the area of a triangle, multiply the height by the width (this is also known as the 'base') then divide by 2.

Can you find the area of a triangle where height = 5 cm and width = 8 cm?

5 脳 8 = 40 梅 2 = 20

The area is 20肠尘虏.
