Best ResponseYou've already chosen the best response.3Ok, so you need half the area of a circle with radius 4 cm. The area of a rectangle is A = LW, where L = length and W = width

Best ResponseYou've already chosen the best response.3Right. Calculate that and divide by 2 because you have only half a circle. Then add that to A = LW, with L = 8 cm and W = 5 cm, which is the area of the rectangle.

Best ResponseYou've already chosen the best response.3That's good. You have the area of the half circle. Now you need to calculate the area of the rectangle and add the two areas.
