Question

The length of a rectangle is 2 cm more than its breadth, and its perimeter is 28 cm. Find the length and
breadth of the rectangle.​

Answer 1

Step-by-step explanation:

Let breadth = x cm

length = ( x + 2 )cm

because length is 2cm more than a breadth

perimeter = 28cm

2 ( l + b ) = 28

2 ( x + x + 2 ) = 28

2 ( 2x + 2 ) = 28

2x + 2 = 28/2

2x + 2 = 14

2x = 14 - 2

2x = 12

x = 12/2 = 6cm

length = x + 2 = 6 +2 = 8cm

breadth = x = 6cm

Answer 2

Answer:

length = 8 breadth = 6

Step-by-step explanation:

perimeter of rectangle = 2(l+b)

let breadth= x

then length = x+2

According to question:

2(x+x+2) = 28cm

2(2x+2) = 28cm

4x+4 = 28cm

4x = 28-4

x = 24/4

x = 6cm

Therefore length = x+2 = 8cm

breadth = x = 6cm
