Find the area of the blue square 20241220

[@FSIec-x3x]

To make it more simple, it is twice the area of the middle square minus the area of the small square, ie 2×10^2-2^2=196

a = 2 + b
(b+2)² + b² = 10²
b² + 4b + 4 + b² = 100
2b² + 4b - 96 = 0
∆ = 16 + 768 = 784
√784 = 28
-4 + 28 /4 = 6
b = 6 > a = 8
A = (6+8)² = 196 cm²

Use Paithagorus theorem and common sense.
8+6=14
14x14=196 easy

Thank you for your comment.
This video gives a solution that even an elementary school student can solve. The solution using Pythagoras theorum would be shown in the next video.

This is easy way to get answer means 14*14=196
