Question

If the area of square 2 is 225units^2 and the perimeter of square 1bis 100. What is the area of square 3

Answer 1

25 square units
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.
