Question

the adjacent sides of a parallelogram are in the ratio 5 is to 3 if the longer of the two sides is 7.5 cm find the perimeter of the parallelogram

Answer 1

let the sides of the ।। gm be 5x and 3x
given that
5x = 7.5 cm
=> x = 1.5 cm
=> 3x = 4.5 cm

=> perimeter of the ।।gm will be
2(7.5+4.5) cm
= 2× 12 cm
= 24 cm
