Question

Find the lenght of a rectangular playground having perimeter 600 metre breadth 90 metre. Should you prefer playing in a playground or playing games on mobile phone?

Answer 1

perimeter=600
breadth =90
then l=?
perimeter =2(l+b)
600=2l+180
600-180=2l
420=2l
l=420/2=210

Answer 2

Given ,

           Perimeter of the rectangular playground = 600 m

           Breadth of the rectangular playground = 90 m

   To find length ,

                            Perimeter of the rectangular playground = 2(l+b)

                                        600 = 2(l+90)

                                         300 - 90 = l

                                       l = 210 m

Therefore, the length is 210 m.

I would prefer to play in the play ground as WHO defines a healthy person as the one who is physically, mentally and socially fit. If I play on the ground then automatically I would be a healthy man.

Playing on mobile phone is wastage of time. As we don't develop any career and life-supporting skills in it.
