Question

The area of a trapezium is 54 sq cm. The length of one of the parallel
side is 10 cm and its height is 4cm. Find the height of the other parallel
side.

Answer 1

Answer:

17 cm

Step-by-step explanation:

area of trap = h(a+b) / 2

or, 54 = 4(10+b) /2

or, 108 / 4 = 10+b

or, 27 -10 = b

or, b = 17.
