Question

The perimeter of rectangle is 13cm and with is 2cm find the length

Answer 1

Answer:

13=2(l+b)

=13=2(l+2)

=13=2l+4

=2l=13-4

=2l=9

=l=9/2

=4.5cm

Answer 2

Let the length of a rectangle be x.

Breadth= 2cm

Perimeter of a rectangle= 13cm

According to the question,

2(x+2)= 13

2x+4=13

2x=9

x=9/2= 4.5

So the length of a rectangle is 4.5cm
