Answer 2

Answer:

length=20

breadth=8

Step-by-step explanation:

length=suppose to be x

breadth=x+12

perimeter=56cm

perimeter of rectangle=2(l+b)

56=2(x+x+12)

56=(2x+12)2

56÷2=2x+12

28-12=2x

16÷2=x

x=8

so, breadth of rectangle is 8

and length of rectangle is x+12=8+12=20

hope it helps you
