If the area of square 2 is 225 units?, and

the perimeter of square 1 is 100 units, what is

the area of square 3?

25 square units

Step-by-step explanation:

square 1 = 100 units (perimeter)

therefore each side = 25 units

square 2 = 225 square units (area)

therefore each side = 15 units

The sequence gradually decreases by 10.

Therefore square 3 each side would be 5 units.

To find the Area = 5*5

= 25 square units.
