Question

Perimeter of a rectangal is 13 cm. If it's width is 11/4 cm , find its length ?​

Answer 1

width=11/4

length= a

perimeter=2(a+b)

13=2( a+11/4)

13/2=a+11/4

13/2 - 11/4=a

(26-11)/4=a

15/4=a

hence length= 15/4

Answer 2

Answer:

HOW MUCH I KNOW I SHARE WITH YOU

Step-by-step explanation:

perimeter of a r rectangle=13cm

2(length + breadth=13

length 11/4 =13/2

length=<13/2- 11/4

length=26/4 - 11/4

length= (26/11)/4

length =15/4

therefore length of rectangle is 15/4 cm
