Question

the perimeter of a rectangle is 13 cm and its breadth is 2 2/3 find its length​

Answer 1

Answer:

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

let lenght be l

now 2¾

=> 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
