Question

Find the sides of a parallelogram whose perimeter is 60 cm and ratio of its sides is

5:7.​

Answer 1

Step-by-step explanation:

let common ratio be x

2(a+b) = perimeter

2× 5x + 7x = 60

2× 12x = 60

24x = 60

x = 60/24

x = 2.5

first side = 5× 2.5 = 12.5 cm

second side = 7× 2.5= 17.5 cm
