Question

The square of $2.8$ is $78.4$. State whether the statement is true (T) or false (F).

• A. True
• B. False

Answer 1

The correct option is B False

The square of $2.8$ is

$={\left(2.8\right)}^2$

We will express $2.8$ in the form of a fraction

$$\begin{gathered} ={\left(\frac{28}{10}\right)}^2 \\ =\frac{784}{100} \\ =7.84 \end{gathered}$$

Hence, the above statement is False.
