Question

the perimeter of a rectangular piece of card board is 6 m.its breadth is 1 m .find its. length ​

Answer 1

Answer:

Let the length be = x

$\color{black}\boxed{\colorbox{saffron}{Perimeter-2(length+breadth) }}$

6=2(x+1)

6= 2x+2

6-2= 2x

4=2x

$\frac{4}{2}$=x

2=x

So, length = 2 m

Answer 2

Answer:

Perimeter of rectangle= 2(l+b)

=2(l+1)=6

= l+1=6\2

=l+1=3

=l=3-1=2

Therefore length of a rectangular piece of board is 2m.

I hope so this answer is helpful for you.
