Answer 1

since angle A is equal to 90 show in triangle ADB and since it is a right angle triangle at a so by Pythagoras Theorem BD is equal to 5 x
and princess BD equal to 10 cm and BD BD equal 25 x 25 X equal to 10 so we get X equal to 2
putting the value of x in the side given for X and 3X we we have a b equal to 8 and ad is equal to 6 Hills the sides of parallelogram are 8 ,6, 8, 6 so the perimeter of parallelogram are is 48 CM
