Question 5 In this figure, if the sidelength of the square is doubled, what is the increase in the areas of the regions 1, 2 and 3? Give reasons.Let side of square be a Thus, Original area of square = a × a = a2 If side of square is doubled New Side = 2a And, New Area = 2a × 2a = 4a2 Thus, if we double the side length of a square, its area gets 4 times bigger Since the whole square becomes 4 times larger, every single region inside it (Regions 1, 2, and 3) also becomes exactly 4 times larger.
