Question
Here are some pictures are drawn on a 1 cm square grid. Try making the same pictures on a 2 cm grid and also on a `1/2` cm grid. One picture is already done.
- The side of the square was made two times bigger. Does its area also become two times bigger?
Diagram
Short Note
Solution
The area of square
= side × side
= side2.
When sides have doubled the area of square
= 2 × Side × 2 × Side
= 4 × side2.
So, when the side of the square is made 2 times bigger, then its area becomes 4 times bigger than the original area.
