Question

What is the area of this trapezoid? units 2

Answer 1

area of trapezoid: 153 units²

Here given information:

• height : 9

• side 1 : 10

• side 2 : 7 + 10 + 7 = 24

trapezium area = $\sf \frac{1}{2}$ * ( side 1 + side 2 ) * height

$\hookrightarrow \sf \dfrac{1}{2} * ( 10 + 24) * 9$

$\hookrightarrow \sf 153 \ units^2$

Answer 2

you’d work out the area of the triangles first so you’d half the base and multiply by the height of it. then multiply that by 2 as there are 2 identical triangles. which gives you 63. then you work out the area of the rectangle which is 90. you then do 90+63 to get 153
