Question

the perimeter of rectungale is 13 cm and its widht is 11 by 4 .find its length

Answer 1

Let the length of the rectangle be xcm.

Given that perimeter of a rectangle = 13cm.

We know that perimeter of a rectangle = 2(l + b).

= > 2(l + b) = 13

Given that width of the rectangle is 11/4

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

= > 2x + 22/4 = 13

= > 2x = 13 - (22/4)

= > 2x = 30/4

= > 8x = 30

= > x = 30/8

= > x = 15/4.



Therefore the length of the rectangle = 15/4 cm.


Hope this helps!

Answer 2

Hey!!

Let the length of rectangle = x

the breadth of rectangle = 11

A/q Perimeter of rectangle = 2 ( l + b )

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

=> 13 cm = 2x + 22 / 4

=> 13 - 22 / 4 cm = 2x

=> 52 - 22/ 4 = 2x

=> 30 / 4 = 2x

=> 30 / 8 = x

=> x = 15 / 4 >>>> Answer

Therefore the length of rectangle is 15 / 4
