Question

Find the area of the shape below, giving your answer to 1 decimal place

Answer 1

`189.25 \: {cm}^(2)`

Explanation:

Area of the shape = Area of rectangle + Area of semicircle.

For rectangle:

Length = 15 cm

Width = 10 cm

For semicircle:

Diameter = 10 cm

Radius = 10/2 = 5 cm

Area of the shape

`= lb + (1)/(2) \pi {r}^(2) \\ \\ = 15 * 10 + (1)/(2) * 3.14 * {(5)}^(2) \\ \\ = 150 + (1)/(2) * 3.14 * 25 \\ \\ = 150 + 39.25 \\ \\ = 189.25 \: {cm}^(2)`

Answer 2
