Question

The area of a trapezium with parallel sides 30 cm and 25 cm and height 5 cm​

Answer 1

Area of the trapezium = 105 cm

One of the parallel sides = 28 cm

Distance between the parallel sides = 5 cm

⇒ Area of the trapezium = 5 2 (28 + b) = 105

⇒ 28 + b = 42

⇒ b = 14

Therefore, length of the other parallel side of the trapezium is 14 cm.
