Question

the perimeter of a rectangle is 104 cm. if it's width is 2 cm more than one third of its length, find the length and breadth of the rectangle.​

Answer 1

Answer:

length    = 51 cm

breadth  = 19 cm

Explanation:

perimeter = 140 cm

let the length be x

thus, breadth =2 + 1x/3

perimeter of rectangle = 2*( length + breadth )

                    140           = 2 ( x + 2+1x/3 )

                     140          = 2x + 4 + 2x/3

                     140-4       =  (6x + 2x) / 3

                     136          =  8x/3

                      136*3      =   8x

                      408 / 8   =   x

                             51     = x

length = 51 cm

breadth = 2+51/3

             = 19 cm
