Question

The length of two parallel sides of a trapezium are 3 cm and 4 cm. Distance between the two parallel sides is 2 cm. Find the area of trapezium.

Answer 1

Answer:

Let the two parallel sides of the trapezium be a cm and b cm.

Given that difference between the two parallel sides is 4 and the perpendicular distance(h) is 19

⇒a−b=4⟶(1)

We know that Area of Trapezium = 21×(a+b)×h

Substituting the values of h we get,

21×(a+b)×19=475

⇒(a+b)=19475×2

⇒a+b=50⟶(2)

Adding (1) and (2),

a−b=4

a+b=50

−2b=−54

b=254=27

Putting b=27 in (2) we get

a+27=50

a=50−27=23

Two parallel sides are 27 cm and 23 cm.
