Make it bigger, Make it smaller
Here are some piuctures drawn on a 1cm square grid. Try making the
same pictures on a 2cm grid and also on a ½cm grid.
1 cm grid ½ cm grid
2 cm grid
The side of the square was made two times bigger. Does its area also
become two times bigger?
Ans: The area of a square = side x side = (side)²
When sides are doubled,
Area of a square = 2 side x 2 side = 4 (side)²
It is clear that when side of a square is doubled, area becomes 4
times the original.
