Find the area enclosed by each of the following figures :

We know that, area of rectangle = l × b

And area of semicircle = × ∏r²

Area of rectangle = 10.2 × 1.5 = 15.3 cm²

Now, Diameter of the semicircle = 10.2 – 3.9 = 6.3 cm

So, radius = = 3.15 cm

Area of semicircle = × × 3.15 × 3.15 = 15.5925 cm²

Total area = Area of rectangle + Area of semicircle = 15.3 + 15.5925 = 30.8925 cm²

∴ Total area = 30.8925 cm²
