The perimeter of a figure is the total distance around the edge of the figure. The area of a flat, or plane figure is the number of unit squares that can be contained within it. The unit square is usually some standard unit, like a square foot or a square inch. I don't really know the rest but I did the first two lol

Find how many oz she ate: 1/2 of 3 is 1.5. 3/4 of 3 is 2.25. 1/2 of 2 is 1. Add all of the oz: 1.5+2.25+1=4.75. She ate 4.75 oz :)
