Question

Q13)The perimeter of a rectangular piece of card board is 6 m. Its breadth is 1 m. Find its length.​

Answer 1

Step-by-step explanation:

perimeter of rec=2(l+b). let length be l

6m =2(l+1)

6 =2l+2

6 - 2 =2l

4/2 =l

2 m = length

Answer 2

Answer:

Let the length be taken as = x

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

6= 2(1+x)

6= 2+2x

6-2= 2x

4÷2=x

2=x

So,

$\rightarrow$Length =2m
