Question

The length of a the length of the parallel sides of a Trapezium is 12cm and 8cm its area is 100 cm square find the distance between the parallel side

Answer 1

the formulae of area of trap. is 1/2(sum of parallel side)×h
by using this formulae
=1/2×(12+8)×h=100
=1/2×20×h=100
=10×h=100
=h=100/10
=h=10cm

Answer 2

Answer:

Given that

parallel sides is equal to 12cm and 8cm

Area is equal to 100sq cm

distance between them is equal to 'x'

The formulae to find the area of a trapezium is

1/2(sum of the parallel sides)(distance between them)

therefore 1/2(12cm+8cm)x=100sq cm

=> 1/2(20cm)x=100sq cm

=>10x cm =100sq cm

=>(by transporting 10 to R. H. S

we get

=>x=100sqcm/10cm

=>x=10cm

therefore the distance between the two parallel sides is 10 cm
