The area of the rectangle is:
length x width
We need to first convert the length and width to the same units. We can convert them to twelfths of a meter, since both 6 and 4 are factors of 12.
Length = 3 and 2/6 meters = 3 x 12/6 + 2/6 = 18/6 + 2/6 = 20/6 = 10/3 twelfths of a meter
Width = 2 and 3/4 meters = 2 x 12/4 + 3/4 = 24/4 + 3/4 = 27/4 twelfths of a meter
Now we can find the area:
Area = length x width = (10/3) x (27/4) = 90/12 = 15/2 = 7.5 square meters
Therefore, the answer is option C) six and five-tenths m² (rounded to one decimal place).
