Answer:15/4Step-by-step explanation:Perimeter given= 13 cm

Width given= 2 3/4 cm = 11/4 cm

Length=?

Perimeter= 2(l+w)

13=2(l+11/4)

13/2=4l+11/4

26=4l+11

15=4l

l=15/4Answer:15/4cm

Step-by-step explanation:hi

The perimeter of a rectangle is 13 cm and its breadth is 2 3/4cm

let lenght be l

now

=> 11/4 cm

perimeter of rectangle = 2(l+b)

so ,

13 = 2(l+b)

13 = 2(l+11/4)

13 = 2l +11/2

13 – 11/2 = 2l

26-11/2 = 2l

15/2 = 2l

=>l= 15/2*2

=>l = 15/4cm

hope it helps u
