Question

Find the area of a right trapezoid with bases 12 cm and 15 cm and a leg of 6 cm?

Answer 1

`81\ cm^2`

Explanation:

The area `A` of a right trapezium with bases i.e. parallel sides `a=12\ cm` & `b=15\ cm` & a leg (i.e. normal distance between parallel sides `a` & `b`) `h=6\ cm` is given by the following formula

`A=1/2ah+1/2bh`

`=1/2(a+b)h`

`=1/2(12+15)(6)`

`=81\ cm^2`
