Question

The area of a trapezium is 1586cm^2 and the distance between its parallel side is 20cm. If one of the parallel sides is 84cm what's the other

Answer 1

Answer:

Area of Trapezium = 1/2 * height * (sum of parallel sides)

                               = 1/2 * 20 * (84 + x)

                               = 10 * (84 + x)

                               = 840 +10x

Therefore, 840 +10x = 1586

                  10x = 746

                  x = 74.6

Therefore length of other side is 74.6 cm
