The area of the shaded region is 212.5 cm²
The area of the shaded region is :
- Area of rectangle- Area of triangle
The area of the rectangle is:
Area of rectangle = 14 × 25 = 350 cm²
Area of triangle is calculated using the formula:
Area of triangle = 0.5 × 12.5 × 11 = 68.75 cm²
For the 2 triangles: (2 × 68.75) = 137.5 cm²
The area of the shaded region = (350 - 137.5) = 212.5 cm²
