Step-by-step explanation:

perimeter = 2(length + breadth)

57 = 2(length + 12.5)

57/2 = length + 12.5

28.5 = length + 12.5

28.5 - 12.5 = length

length = 16

Answer 2

Answer:

16cm

Step-by-step explanation:

Perimeter of rectangle= 2(l+b)

2(l+b)=57cm

(Let the length be x)

2(x+12.5)=57cm

x+12.5=57/2

x+12.5=28.5

x=28.5-12.5

x=16cm ( Length of the rectangle)
