Question

if you know that then please rply me ​

Answer 1

Step-by-step explanation:

Perimeter of Rectangle=40m

Let the breadth be x

Length=x+4.

Now,

2(L+B)=40

2(2x+4)=40

4x+8=40

4x=32

x=8.

Now,

Breadth=8

Length=8+4=12.

HOPE IT HELPA YOU.

Answer 2

breadth =x

given that:- perimeter of rectangle is=40m

and,the length is 4m more than the breadth=x+4

then,we know that

perimeter of rectangle=2(l+b)

40=2(x+4+x)

40=2(2x+4)

40=4x+8

40-8=4x

32=4x

4x=32

•°•x=32/4

x=8

breadth =8m (ans.)
