Area of field = 25*12= 300 sqm
Area of house = 9*9 = 81 sqm
Area of garden=300-81=219 sqm
Hence Ans is A

Hello experts!

I know how to approach this concept but..

Maybe this sounds a bit obvious but I would like to know which is the concept behind the incorrect solving like the following:

25-9 = 16
12-9 = 3

16*3 =48
