14.) I agree. This parallelogram has an area of 6*7 = 42. Drawing a parallelogram with side lengths which two numbers (not 6 and 7) that multiply to 42 would have the same area. 2 * 21 = 42. You can draw a parallelogram that is 2 by 21 and it will have the same area.
15.) The area of a parallelogram is found by A = b*h. Since the base and height are 8 and 3, then the area is 8*3 = 24. One parallelogram is 24. Since there are 8 in total to make the shape, then the area is 8*24 = 192.
