Today in maths, we are going to be learning how to find the area of a triangle.


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


h x w ÷ 2


For example:

If a triangle had a height of 5cm and a width of 8cm you would do the following calculation to find the area of the triangle:

5 x 8 = 40 ÷ 2 = 20

The area is 20cm2


Now it’s your turn!
