Question
How many squares will be in the 5th figure?
- 63
- 70
- 60
- 77
Hint:
From the patttern we cajn observe that
in each stage iyt is going as follows
1st figure : It is 2 by 3 ..2 × 3 = 6 squares
2nd figure: It is 4 by 4 .. 4 × 4 = 16 squares
3rd figure: It is 6 by 5 .. 6 × 5 = 30 squares
4th figure: It is 8 by 6.. 8 × 6 = 48 squares
So from this we can tell that
5th figure: It is 10 by 7.. 10 × 7 = 70 squares
The correct answer is: 70
In the question we were given with a pattern consisting of squares with each square has different no of squares inside.
We observed first four figures carefully and then obtained a relaton to find no of squares in 5th figure = 70
