Question

the perimeter of a rectangle is 12 cm and its width is 2 m find its length​

Answer 1

Answer:

we know perimeter of a rectangle=2(l+b)

so

2(l+b)=12

2(l+2)=12

2l+4=12

2l=12-4=8

2l=8

l=8/2=4

that is the length is 4 cm

Answer 2

Step-by-step explanation:

Perimeter=12

Breadth= 2

Let Length be x

Perimeter=2(l+b)

12=2×(2+x)

12/2=2+x
