Answer 1

Answer:

The length of a rectangle is 7/5 of its breadth, if its perimeter is 48 cms, then what is its length?

Let breadth be x

Length=7/5 *x=7x/5

perimeter of rectangle=2(l+b)=2(7x/5+x)

given,perimeter=48cms

2(7x/5+x)=48

7x/5+x=48/2=24

(7x+5x)/5=24

12x/5=24

x=24×5/12

x=10cms i.e., breadth=10cms

length=7*x/5=7×10/5=14 cms
