Question

the perimeter of a trapezium is 52 cm . if its non parallel sides are 10cm each and its altitude is 8cm ,find the area of trapezium .

Answer 1

Perimeter of a trapezium is 52cm sum of non parallel sides are 10cm +10 cm =20 cm sum of parallel sides =52-20 =32 area=(1/2)*(32)*(12) =144 sq units.

Answer 2

perimeter of trap.= sum of parallel sides + sum of non parallel sides
52=sum of parallel sides +10+10
52-20=sum of parallel sides
32=sum of parallel sides

now area of trap.=1/2×height×(sum of parallel sides)
=1/2×8×32
=4×32
=128cm2
