Question

the perimeter of rectangle is 12cm and its breadth is 2 3/4cm find its length​

Answer 1

Answer:

1/4=0.25

Step-by-step explanation:

Since its a rectangle

Perimeter =2(l+b)

12=2(l+b)

6=l+b

Breadth =23/4

6=l+23/4

6-23/4=l

1/4=length

Answer 2

hey brainly user

here is ur answer

Step-by-step explanation:

$perimeter \: of \: rectangle = 12cm$

$breadth = 2 \frac{3}{4} = \frac{11}{4}$

$2(l + b) = 12$

$= > 2( \frac{11}{4} + l) = 12$

$= > \frac{11}{2} + 2l = 12$

$2l = 12 - \frac{11}{2} = > l = \frac{13}{4} cm$

hope the answer helps
