To find the area of all of the figures, all you need to do is base x height or the length x width. Your answers for 1-6 are all correct. For 7-9, remember that the area is the length times the width. 7) length x width, 42 x 30=1260 8) 17 x 22= 374 9) Since the length and width are the same in a square just multiply the side by itself. 2.7 x 2.7= 7.29 Hope this helps.
