Its 272ft sq because if it is the area you can dig then you have to take away the No digging part and multiply the parts where you can dig.
Assuming that the room is rectangle and carpet is rectangle
area=legnth times width
legnth=longer than width
12 is longer than 8
12ft=legnth
8ft=width
now convert to yards
1 yard=3 feet
1 foot=1/3 yard
12 ft times 1/3=4yards
8 ft times 1/3=8/3yards
multiply
area=4 tiimes 8/3
area=32/3
area=10 and 2/3 square yards
Answer:
83
Step-by-step explanation:
82+87+83+77+70+80+88= 567
Then you divide that answer by the number of numbers you added by which is 7.
567/7= 81 so 83 was the missing number
