 A circle is drawn inside a trapezium such that it touches all the four sides of the trapezium. The line joining the midpoints of the non-parallel sides divides the trapezium in two parts with areas in the ratio 3 : 5. If the lengths of the non-parallel sides are 6 cm and 10 cm, then what is the ratio of the length (in cm) of the smaller side to the longer parallel sides of the trapezium? 


A) 3:4

B)1:2

C)1:3

You could create a quadratic and solve, but simpler to just do trial and error. Either you make 5, 20, 5 or 10, 10, 10 as the 3 sides since 5x20 or 10x10 gives 100.

it should be 5 not 10 because if we consider 10m as width then the shape of the garden will become a square

Medians divide traingles into smaller one of equal area.hence srra of BGD is 90/6=15
