1. The perimeter of rectangle is 13 cm and its width is 2 whole 3 upon 4 centimetre find its length​

Answer 1

Answer:3 $\frac{3}{4}$ cm

Step-by-step explanation:

let the length be x

p = 2(l+b)

13 = 2(l+2$\frac{3}{4}$)

13 = 2l +2* 2$\frac{3}{4}$

13 = 2l + 2* $\frac{11}{4}$

13 = 2l  + $\frac{22}{4}$

13  - $\frac{22}{4}$ = 2l

$\frac{52-22}{ 4}$ = 2l

$\frac{30}{4}$ =2l

l = $\frac{30}{8}$

l =3 $\frac{3}{4}$ cm
