Question

in a trapezium one of its parallel side is 15 m more than that of other.area of trapezium is 21000 cm square and its height is 105 mtr.find its parallel side

Answer 1

Answer: parallel sides are 192.5 & 207.5

explanation:

Let one parallel side be P and other be (P + 15)

Area of Trapezium = (Sum of parallel sides) x height/2

given height = 105m

area = 21000 m²

21000 = (P + P + 15) x 105/2

2P + 15 = 400

2P = 385

P =  192.5

P + 15 = 207.5
