Question

The perimeter of a rectangle is 36 cm.
If its length is 4 cm more than its breadth,
find the length of the rectangle.​

Answer 1

Answer:

Step-by-step explanation:

Let the breadth be x.

length= x+4 cm

perimeter= 2(x+x+4)

               = 4x+8

       BTP

4x+8 = 36

4x = 28

x = 7

∴ length of triangle = 11 cm

Answer 2

Answer:

HOPE , THIS WILL HELP YOU.

Step-by-step explanation:

RECTANGLE:

let breadth = x cm

therefore,length = (x+4) cm

we know that perimeter of rectangle = 2(l+b)

according to question,

perimeter = 2(l+b)

   36      =  2(x+4+x)

   36/2  = 2x+4

    18      = 2x+4

 18-4     = 2x

   14      = 2x

 14/2   = x

  7 = x

breadth = x cm = 7 cm

length = (x+4) cm = 7+4 = 11 cm
