Answer:
Perimeter,p= 125 cm
Breadth,b= ?
Length,l= 4b
Now, p =2(l+b)
125 = 2*(4b+b)
125 = 2*(5b)
125 = 10b
b = 125/10
b = 12.5 cm
Now, l = 4b
l = (4*12.5)cm
l = 50 cm

Step-by-step explanation:
For this rectangle ,
breadth = x
length = 4x
perimeter = 2 × ( length + breadth )
125 = 2 ( 4x + x )
5x = 125/2
x = 25/2 = 12.5 m
So , breadth = 12.5 m
& length = 4(12.5) = 50 m
