Question

C) The area of a trapezium is 480 cm2, the distance between two parallel sides is 15 cm and one of

the parallel side is 20 cm. The other parallel side is:
a) 20cm b) 34 cm c) 44 cm d) 50 cm​

Answer 1

The answer is c) 44 cm

Explanation:

480= 20+b/2 x 15

480 x 2 = 20 + b x 15

960/15 = 20 + b

64 = 20+ b

64- 20 = b

44 = b

Hence the other parallel side is 44 cm
