Question

the area of a Trapezium is 180 cm square and its height is 12 CM if one of the parallel sides is double The Other find the lengths of the parallel sides​

Answer 1

180 = 1/2(x +2x)(12)

30=3x = x = 10

Sides are 10& 20cm

Answer 2

area of trapezium= 1/2 (a+b)h

180 =1/2(a+2a)12

180=(3a)6

18a=180

a =180/18=10

therefore the parallel sides are 10&20 cm respectively
