Question

31. The area of a trapezium is
828 sq.cm. If the length of its
parallel sides are 19.6cm and 1.
4 cm, find the distance
between them.​

Answer 1

Answer:

Area of trapezium =160 m

2

The ratio of the length of its parallel sides =1:3

Smaller parallel sides =10 cm

∴ Length of greater side =10×3=30 cm

Let the distance between them =h

We know that,

Area =

2

1

× sum of parallel sides × height

⇒160=

2

1

(30+10)h

⇒160×2=40h

⇒h=

40

320

=8 cm
