Santosh painted a scenery on a square Canvas of side 2 dm. Shanthi also painted a scenery on a square Canvas of side twice that of Santosh's. How many times the size (the area) of Canvas used by Shanthi is greater than that used by Santosh.
Area of Canvas drawn by Santhosh = 2 x2 = 4 dm² Area of Canvas drawn by Shanthi =4 x 4 = 16 dm²
Hence Ratio = 4/16 = 1:4
Hence Canvas of Shanthi is 4 times bigger than Santhosh
