Question

find the area of this square:
square meters

Explanation:

Step1: Recall the area formula for a square

The area formula for a square is $A = s^2$, where $s$ is the side - length of the square.

Step2: Substitute the side - length into the formula

Here, $s=\frac{2}{5}$ m. So $A = (\frac{2}{5})^2$.

Step3: Calculate the square of the fraction

Using the rule $(a/b)^2=a^{2}/b^{2}$, we have $(\frac{2}{5})^2=\frac{2^{2}}{5^{2}}=\frac{4}{25}$.

Answer:

$\frac{4}{25}$
