C-112

Ans 2:

Class : Class 3
yeah..... The answer is 112 and it has given the solution in the context of X only. I guessed the answer and it was right. However, I would be very grateful if you could explain in an easier and quicker method. I understood the solution but you could always provide me with a quicker method because of this question cam it would require a lot of time.

[C] see there are 4 sides each divided into 4 parts therefore total no. of divisions:- 4*4 = 16 considering each side as a and length for one side as l we have l^2 = a^2 + (a/16)^2 now you can find the length for all 4 sides.
