Answer:

Given , length = 15m, breadth = 10m

perimeter = 2(l+b) = 2(15+10)=2×25=50m

let length of a rectangle = 4x m

breadth of rectangle = 1xm

perimeter of rectangle = 50m

2(l+b)=50

2(4x+1x)=50

5x=50/2=25

x=25/5=5

length = 4x=4×5=20

Breadth =1x=1×5=5

Hence breadth is 5m and length is 20m.
