If the breadth of rectangle is one-fourth of its length and perimeter in60 CM find the length and breadth of rectangle

Step-by-step explanation:

Let length be x

So breadth will be 1/4x

2(x+1/4x)=60

x+1/4x=60/2=30

find lcm and the lcm would be 4 and make denominators equal and add it

4/4x+1/4x=30

5/4x=30

x=30*4/50=6*4=24

Therefore the length is 24/4=6cm and breadth is 24cm.
