Question

the ratio of the sides of the parrallelogram and its perimeter is 70cm find sides

Answer 1

uh forgot to write the ratio LOL

Let them in the form of x = 3 x : 4 x  

Now , Perimeter = 70 cm  

2(l+b) = 70 cm

2(3x+4x) = 70 cm  

2(7x) = 70 cm  

7x = 70/2

7 x = 35 cm  

x = 5 cm

Now ,  

3 x = 3× 5 cm = 15 cm  

4 x = 4× 5 cm = 20 cm
