You have to convert all terms to inches so that they are all like terms, there are 12 inches in a foot so you multiply everything by 12. You dont multiply the 10 inches though because its already in inches
6x12=72 8x12=96 2x12=24
Then you multiply to find the areas of the large shape. It was the 6ft and 8ft so you multiply the 72 and 96
72x96=6912
Then you multiply to find the smaller shape. It was the 2 and 10 so do 24 times 10.
24 x 10= 240
then you divide 240 by 12 to get to the feet so it
240/12 = 20ft
