Area of the figure = Area of rectangle + area of semi-circle

Area of rectangle = a * b = 6 * 2 = 12 m²

Area of the semi-circle = πr²/2 = 3.14 * (1.5)²/2
A = 3.53

Area of figure = 12 + 3.53 = 15.53 m²

In short, Your Final Answer would be: 15.53 m²

Hope this helps!

Answer:


15.5\ m^(2)

Explanation:

we know that

The area of the figure is equal to the area of a rectangle plus the area of semicircle

Step 1

Find the area of the rectangle

The area of the rectangle is equal to


A=bh

we have


b=6\ m


h=2\ m

substitute


A=6*2=12\ m^(2)

Step 2

Find the area of semicircle

The area of semicircle is equal to


A=(1)/(2)\pi r^(2)

we have


r=3/2=1.5\ m

substitute


A=(1)/(2)(3.14)(1.5^(2))=3.5\ m^(2)

Step 3

Find the area of the figure


12\ m^(2)+3.5\ m^(2)=15.5\ m^(2)
