All of the quadrilaterals in the shape below are squares. Find the area of the shaded region.

To find area of square one :-Given :side = 9 (unit)To find :Area of squareWe know :Area of square = side²Therefore:-→Area of square = 9²→Area of square = 9 × 9→Area of square = 81 (unit)²To find area of square two :-Given :side = 11 (unit)To find :Area of squareWe know :Area of square = side²Therefore:-→Area of square = 11²→Area of square = 11 × 11→Area of square = 121 (unit)²Now it's clearly visible that the whole figure is also. a square .Therefore AE = CPWhich means area of square three = 81 (unit)²Now area of shaded figure :-Area of square one + Area of square two + Area of square three81 + 81 + 121283 (unit)²
