Answer 2

Answer:

Let the length of the other parallel side be b.

Length of one parallel side, a = 10 cm

height, (h) = 4 cm and

The area of a trapezium is 34 cm^2cm

2

Formula for, Area of trapezium = 1/2 (a + b) h

34 = ½(10+b) x 4

34 = 2(10 + b)

After simplifying, b = 7

Hence another required parallel side is 7 cm.
