Step-by-step explanation: Notice that the figure shown here is a rectangle so we can find its area by using the formula length x width.
Since the length is 3/7 in and the width is 2/8 in, we can plug this information into the formula to get (3/7)(2/8).
Now multiplying across the numerators and multiplying across the denominators we get 6/56 which can be reduced to 3/28 inĀ².
