Answer:
Assuption: Let the common ratio of the sides be x.
then, length=5x
breadth=2x
peri.= 2(l+b)=2(7x)
70=14x
x=70/14=7/2cm
length= 5x=7/2×5=35/2cm.
Breadth=2x=14/2cm

Given,
- Sides of Parallelogram are given in ratio 5:2
- Perimeter = 70 cm
To find :
Length of sides of Parallelogram
How to find :
At first we will let the ratio in x. Then, will equate both. From this we will find x. Then we will multiply with the given ratio and will get the length of two sides.

Solution :
Let the sides be 5x and 2x
Perimeter = 70 cm
A/Q
So,
5x = 5 × 5 = 25 cm
2x = 2×2 = 4 cm
Henceforth,
The length of the two sides are 25 cm and 4 cm.
