Question
The area of a trapezium is 140 cm² and the
perpendicular distance between its parallel sides is 7 cm. If the length of one of the parallel sides is 28 cm, what is the length of the other parallel side?Solution
Let the length of the other parallel side be a cm. According to the question, (a+28)/2 x 7 = 140 (a+28)/2 = 140/7 (a+28)/2 = 20 (a+28) = 40 Â a = 12 The length of the other parallel side is 12 cm.
