Answer:
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
= <u>25 square units.</u>
