Question

The area of trapezium is 34 sq .m and length of one of parallel side is10 cm and its height is 14 cm .Find the length of other parallel side.​

Answer 1

Given:-

• area of trapezium is 34 sq cm

• length of one of parallel side is10 cm

• height is 4 cm.

To Find:-

• the length of other parallel side.

Solution:-

let the lengths of parallel sides = 10cm and b cm

height = 4cm

area = $\frac{1}{2}$× (10+b) × 4

34 = 2 × (10+b)

10+b = 34/2 = 17

b = 17 - 10 = 7cm

the length of the other parallel side is 7cm
