The perimeter of one square is 36cm and the perimeter of the second square is 28cm.

The perimeter of one square is 36cm and the perimeter of the second square is 28cm. How many square centimeters the area of the first square is larger than the area of the second.

1. Determine the size of the side of the first square:

36: 4 = 9 cm;

2. Determine the size of the side of the second square:

28: 4 = 7 cm.

3. Determine the area of the first square:

9 x 9 = 81 cm²;

4. Determine the area of the second square:

7 x 7 = 49 cm²;

5. Determine how many cm² the area of the first square is larger:

81 – 49 = 32 cm².

Answer: the area of the first square is 32 cm² larger.
