Question

the perimeter of a rectangle is 13cm and widht is 11/4 cm find the length​

Answer 1

Answer:??

Step-by-step explanation:so given is 2(l+b)=13

Then 2(x+x*11/4)=13

2x+11x/4*2=13

2x+11x/2=13

(4x+11x)/2=13

15x/2=13

X=26/15

Answer 2

Answer:

Step-by-step explanation:

Perimeter= 2(length+breadth)

13cm= 2(x+11/4cm)

13cm= 2x+(2*11/4cm)

13cm= 2x+11/2cm

2x= 13cm-11/2cm

LCM(1,2)=2

2x= 26/2cm-11/2cm

2x= 15/2cm

x= 15/2cm÷2

x= 15/2cm*1/2

x= 15/4cm or 3mixed¾
