Question

2. The area of a trapezium is 34 cm' and the length of one of the parallel sides is
10 cm and its height is 4 cm Find the length of the other parallel side.​

Answer 1

Answer:

area of trapezium = 1/2 * h ( a + b )

34 = 1/2 * 4 ( 10 + b )

34 = 2 ( 10 + b )

34 = 20 + 2b

2b = 34 - 20

2b = 14

b = 14/2

b = 7

Therefore, length of the other parallel side is 7cm.
