you need to find 3 areas here. it's best to find the area of each rectangle which is really easy. the top and bottom one are 66 ft each but there's 2 of them so 66+66=132 the one on the left and right are 54 each, so 108 in total for those 2. the last ones front and back are 99 each so 198 total. add the totals and you get B. 438 ft2
