Question

The area of a trapezium is 36 cm2 the distance between its parallel is 4cm the distance between its parallel is 4cm. if one of the parallel sides is 7 cm then find the other parallel side.

Answer 1

Solution :

Given : Area of Trapezium = 36 cm^2.

Distance Between its parallel = 4cm.

1st Side among parallel side = 7cm.

To Find : Length of the other parallel side.

Let the other side be 'x'.

=> Area of Trapezium = 1/2 (Sum of Parallel Sides) × Height.

=> 36 = 1/2 (7 + x) (4)

=> 36 = (7 + x) (2)

=> 36 = 14 + 2x

=> -2x = 14 - 36

=> -2x = -22

=> x = 11

Therefore, the length of other side is 11 cm.
