Trapezium

The parallel sides of a trapezium are 3 cms and 9 cms . The non- parallel sides are 4 cms and 6 cms. A line parallel to the base divides  the trapezium into two trapeziums of equal perimeters. Find the ratio in which each of the non-parallel sides is divided.

Re: Trapezium

Assume the ratio as x:1 and equate the perimeters.The internal side being common to both can just be cancelled ,no calculation of that side is necessary.

Re: Trapezium

hi iamaditya

a + d = 4
b + c = 6

I only got one solution, same as thickhead.

How did you get these 2 equations?
