Question

The perimeter of a rectangle is 13 cm and its width 2,3÷4cm find its length

Answer 1

Width = 2 3/4 cm = 11/4 cm




Given, perimeter = 13

2( length + 11/4 ) = 13

2length + 11/2 = 13

2 length = 15/2

length = 15/4 cm

Answer 2

Heya !!






Let length of rectangle be X cm.


Breadth of rectangle = 2 3/4 = 11/4 cm.




Perimeter of rectangle = 13 cm



2 ( L + B ) = 13


2 ( X + 11/4 ) = 13




2 ( 4X + 11 /4 ) = 13




4X + 11 /2 = 13




4X + 11 = 26



4X = 26 - 11


X = 15/4 cm.



Length of rectangle = X = 15/4 cm.
