okay welcome to our math session with me

Sarah green on how to find the area of a

right-angled triangle finding the area

of a right-angled triangle is very easy

there is a simple formula base x height

divided by 2 let's have a look at how it

works

here is a right-angled triangle the base

is 5 centimeters and the height is 6

centimeters take those two numbers and

multiply them together we get 30

centimeters squared now divide 30 by 2

the area of the triangle is 15

centimeters squared how does this work

any right-angled triangle can be turned

into a quadrilateral a four-sided shape

where the opposite sides are of equal

length to find the area of a

quadrilateral you simply multiply the

place by the height because our

triangles are half a rectangle we have

our answer simple isn't it so to find

the area of a right angle triangle

multiply the base by the height then

divide your answer by 2
