Question

perimeter of a rectangle is 13 if it's width is 11/4 find its length ​

Answer 1

Answer:

3.75

Step-by-step explanation:

Perimeter = 13

width = 11/4

We know,

perimeter of a rectangle= 2( l + b)

Therefore, 13 = 2l + 2x 11/4

13= 2l + 11/2

13 — 11/2 = 2l

15/2= 2l

Therefore l = 3.75

Answer 2

Answer:

15/4

Step-by-step explanation:

PERIMETER OF THE RECTANGLE= 13

A/Q, WIDTH= 11/4

WE KNOW THAT:-

PERIMETER OF A RECTANGLE= 2(l+b)

⇒2(l+b)= 13

⇒2(l+11/4)=13

⇒2[(4l+11)/4]=13

⇒(4l+11)÷2=13

⇒4l+11=13×2

⇒4l+11=26

⇒4l=26-11

⇒4l=15

∴l=15/4

                                     LENGTH OF THE RECTANGLE=15/4

HOPE THIS HELPS! :)
