Question

The area of rectangle is 15 times of the sum of its length and breadth what is permieter of rectangle

Answer 1

Given AREA OF rectangle = 15 ( length+breadth)

l*b= 15 (l+b)

l+b= (l*b)/15---------------------(1)

Perimeter of rectangle = 2(l+b)

                                     = 2(l*b)/15  from (1)

                                     = 2/15(l*b)
