The area of a trapezium is 40 cm². Its parallel sides are 12 cm and 8 cm. The distance between the parallel sides is
Answer & explanation
Correct answer: option 4
The distance between the parallel sides is height of the trapezium.
Area of a trapezium = \(\frac{\text{Sum of parallel sides}}{2 }\) x height
40 = \(\frac{\text{12 + 8}}{2 }\) x h
40 = \(\frac{\text{20}}{2 }\) x h
40 = 10h
h = 4 cm
