Question

The length and breadth of a rectangle are in 15:11 ratio.if the length is 56 cm more then the breadth find the perimeter of rectangle​

Answer 1

528 cm.

process:

let the l and b be 15x and 11x

therefore, 15x-11x=56cm

=> 14

15x= 15×14=210

11x= 11×14= 154

perimeter:

2(l+b)

= 2×264

=528
