Question

A figure is formed by overlapping three identical squares.Point A,B and C are the centres of the square. The total area of the figure is 90cm square. What is the perimeter of the figure?​

Answer 1

Answer:

Let the side of each square be x.

So, perimeter of figure P = 12x

⇒240=12x⇒x=20cm

∴ Perimeter of figure Q = 10x

= 10×20=200cm

Answer 2

Conclusion
