Question

(a) How many small squares of size 1 cm are there in this big green square?
(b) Can you think of a faster way to know the total number of small squares without conting each?

Answer 1

(a)
There are 36 small squares in the big green square.

(b)
Number of squares in the first row = 6
Number of rows = 6
Now, we see that each row contains the same number of squares.
∴ Total number of squares in 6 rows = 6 × 6
= 36
