John bought a square plot of 60 m. Adjacent to this David bought a rectangular plot of dimension 70 m x 50 m. Both paid the same amount. Who is benefited?

To find who is benefited, we have to find the area of above shapes separately.

(i) ABFG is a square of side length 60 m

(ii) BCDE is a rectangle of length 70 m and width 50 m.

Area of square = a²

Area of rectangle = length x breadth

Area of ABFG = 60² = 60 x 60 = 3600 m²

Area of rectangle = 70 x 50 = 3500 m²

From the above calculation, we come to know that John is having more area than David. So John is more benefited.

You would plot 83 on the 83 line and you would plot -113 on the -113 line.
