Question

the peremeter of rectangle is 20m its breath is 2m.less then its length what is length and breath​

Answer 1

Answer:

Let the length be x

Then breadth=2+x

Perimeter=2(l+b)=20m

That is,

2(x+2+x)=20

2(2x+2)=20

4x+4=20

4x=20-4

4x=16

x=16/4=4

x=4

Length=x=4m

Breadth=x+2=4+2=6m

Hope it help you...

Answer 2

Answer:

length= 2+y

breadth=y

perimeter= 2(l+b)

20= 4+2y +2y

16=4y

y=4

breadth = 4

length= 6
