40.26 ft^2
The area of a triangle is equal to the length of the base multiplied by the height then divided by 2. The length of the base is 6, the height is 4 putting it into the formula 6 x 4 divided by 2 is 12, thus the area of the triangle is 12 ft^2. The area of a circle is given by pi multiplied by the radius^2 the radius is 3 so plugging it into the formula 3 x 3 x 3.14= 28.26 ft^2 is the area of the circle add the area of the circle and triangle together and 28.26 + 12 is 40.26 ft^2
