Question

Find the Shaded Region

Answer 1

@Luis_Rivera That is incorrect.

Answer 2

its good to know someone actually understood that thought processes behind the solution !!

Answer 3

The diagonal of the large square is 18. The area of a square with a diagonal is x^2/2 where x is the diagonal. Hence the area of the largest square is 18^2/2 = 162. The area of the small square is equal to the 4 triangles. Each triangle has an area (b*h)/2. Since the triangles are right isosceles triangles, the area is (4*4) / 2 = 8. Since there is 4 of them, the area of the small square is 32.

Therefore, the area of the shaded region is:
area of large square - area of small square = 162 - 32 = 130
