Question

2
The area of a trapezium is 400 cm2, the distance between the
parallel sides is 16 cm. If one of the parallel sides is 20 cm, find the
length of the other side.​

Answer 1

Answer:

30cm is the length of the other side.

Step-by-step explanation:

h(a+b)/2

=> 16(20+b)/2 = 400cm²

=> 320 + 16b = 400 x 2

=> 16b = 800 - 320

=> b = 480/16

b = 30cm
