Question

The perimeterof a rectangle is 130 cm if breadth of the rectange is 30 cm find the length

Answer 1

Hey!!


Let the length of the rectangle be x cm

and the breadth of the rectangle be 30 cm

A / q


Perimeter of a rectangle = 2 ( l + b )

=> 130 cm = 2 ( x + 30 )

=> 130 cm = 2x + 60

=> 130 - 60 cm = 2x

=> 70 cm = 2x

=> 70 / 2 cm = x

=> x = 35 cm


Therefore the length of the rectangle is 35 cm





Hope it will helps you!

Answer 2

LET LENGTH BE x

=> 130 cm = 2 ( x + 30 )  

=> 130 cm = 2x + 60  

=> 130 - 60 cm = 2x  

=> 70 cm = 2x

=> 70 / 2 cm = x  

=> x = 35 cm
