Answer 1

Answer:

Here is ur answer

Step-by-step explanation:

Let 'l' and 'b' the length and width of the rectangle respectively.

Given, b=2

4

3

cm

=

4

11

cm

and perimeter of the rectangle = 13 cm

2(l+b)=13

⇒2l+2b=13

⇒2l+2(

4

11

)=13

⇒2l+

11

=13

⇒2l=13−

15

cm

∴ length of the rectangle =

15cm

Answer 2

Answer:

here

Step-by-step explanation:

Perimeter=13cm

width= 2×3/4= 11/4

length= x

perimeter of rectangle=2×(l+b)

13= 2×(x+11/4)

13-11/4= 2x

63/4=2x

63/4/2/1= x

63/8= x
