Question

The side of the square was made two times bigger. Does its area also become two times bigger? (3 Marks)

Answer 1

Solution:

Suppose the original length of side of square is 1 cm. Now, area of square = side × side = 1 × 1 square cm = 1 square cm (1 Mark)

When the side of square is made two times bigger, then the new length of the side of the square will be 2 cm Area of square = side × side = 2 × 2 square cm = 4 square cm (1 Mark)

So, when the side of the square is made 2 times bigger, then its area becomes 4 times bigger than the original area. (1 Mark)
