Question

The perimeter of a trapezium is 52cm. It's non-parallel are 10 cm each and the distance between two parallel sides is 8cm. Find the area of the trapezium.

Answer 1

It's non parallel sides are of 10 cm each. It means sum of parallel sides is 32cm.
Area = 1/2 × h × ( Sum of parallel sides )
= 1/2 × 8 × 32
= 128cm ^ 2

Answer 2

area of tapezium
$= 1 \div 2 \times sum \: of \: parralel \: sides \times height$
$sum \: of \: prallel \: sides = perieter - sumof \: non \: parallel \: sides$
