Question

The perimeter of a rectangle field is 54 m. if the breadth is 12m, then its length​

Answer 1

length of rectangle = 1/2 x perimeter of rectangle - breadth

27 - 12 = 15 m is the length of rectangle

Answer 2

Answer:

let length be x m. then

perimeter =2(l+b)

54=2(x+12)

54=2x+24

2x=54-24

2x=30

x=15

then length is 15 m.
