Answer 1

Answer:

(a) Area of Shaded Region = Area of Rectangle - (Area of 2 Triangles

• Area of Rectangle = 10 × 6 = 60cm²
• Area of Upper Triangle = (1/2)×5×5 = 25/2cm²
• Area of Lower Triangle = (1/2)×3×3 = 9/2cm²

Area of Shaded Region = 60 - [(25/2)+(9/2)] = 43cm²

(b)Area of Shaded Region = Area of Square - 4(Area of Triangle)

• Area of Square = 8 × 8 = 64cm²
• Area of Triangle = (1/2)×4×4 = 8cm²

Area of Shaded Region = 64 - 4(8) = 64 - 32 = 32cm²
