Step-by-Step Solution

To solve the problem of finding the area of a square with a side length of 213 2\frac{1}{3} , we follow these steps:

  • Step 1: Convert the side length to an improper fraction.
  • Step 2: Use the formula for the area of a square.
  • Step 3: Perform the necessary calculations and simplify.

Let's begin:

Step 1: Convert the mixed number 213 2\frac{1}{3} into an improper fraction. The conversion process involves multiplying the whole number part by the denominator and then adding the numerator:
213=2×3+13=73 2\frac{1}{3} = \frac{2 \times 3 + 1}{3} = \frac{7}{3} .

Step 2: Use the area formula for a square, which is Area=side2 \text{Area} = \text{side}^2 . Here, the side length is 73 \frac{7}{3} , so we calculate:
Area=(73)2=7×73×3=499\text{Area} = \left(\frac{7}{3}\right)^2 = \frac{7 \times 7}{3 \times 3} = \frac{49}{9} .

Step 3: Simplify or convert the improper fraction to a mixed number:
499\frac{49}{9} can be written as the mixed number 549 5\frac{4}{9} .

Therefore, the area of the square is 549 5\frac{4}{9} .

Answer

549 5\frac{4}{9}
