Question

The adjacent sides of a parallelogram in the ratio 5:3 . if the longer of the two sides is 7.5cm , find the perimeter of the parallelogram​

Answer 1

Answer:

24cm

Step-by-step explanation:

let the sides are in the ratio 5x:3x

as there is longest side is 5x

and it is also given 7.5cm

so acc. to ques.

5x = 7.5

x = 7.5/5

x = 1.5cm

so longest side = 5×1.5 = 7.5

and smallest side = 3×1.5 = 4.5

as we know perimeter of parallelogram = 2(a+b)

so,, 2(7.5+4.5)

= 2×12

= 24cm ....ans.
