Hello!
To find the area of a triangle, first multiply the base by the height. Afterwards, divide the product by 2.
Base: The bottom side of the triangle.
Height: The distance from the bottom to the top of the triangle.
Base = 13
Height = 18.2
13 × 18.2 = 236.6
Now we do the final step, which is to divide by 2.
236.6 ÷ 2 = 118.3
118.3 is your answer.
But why do we divide the product of the base and the height by 2? This is because a triangle is recognized as half of a rectangle/square.
