A rectangular piece of paper of dimension 4 cm × 3 cm was cut from a rectangular sheet of paper of dimensions 10 cm × 6 cm. Find the ratio of the areas of the two rectangles.

Given, length of sheet of paper = 10 cm

breadth of sheet of paper = 6 cm

Area = l x b = 10 x 6 = 60 cm²

Now, length of smaller paper = 4 cm

breadth of smaller paper = 3 cm

Area = 4 x 3 = 12 cm²

Ratio of areas of two rectangles = 60 cm² : 12 cm² = 5 : 1
