Question

the perimeter of rectangle is 13 cm nd it's width 11 /4 cm .find its length.​

Answer 1

Step-by-step explanation:

2( x+y) = 13

2( 11/4 + y) = 13

11/4 + y = 13/2

y = 13/2 - 11/4

y = (26 - 11)/4

y = 13/4

Answer 2

Answer:

let length be x

perimeter = 2 (x+11/4)

13 = 2x + 11/4 × 2

13 = 2x +11/2

13×2 = 2x + 11

26 - 11 = 2x

15 = 2x

15/2 = x

7.5 = x
