Hi there!
To solve this problem, we need to first convert 1.2 m into cm, and then find the area of the square sheet of paper, before dividing it by 2 cm squared pieces of paper to get the answer.
1 m = 100 cm
1.2 m = 120 cm
120 × 120 = 14400
14400 ÷ 2 = 7200
So, your answer is 7200.
Hope this helps!
