Question

Type the correct answer in each box.The area of a square is given by s^2 and the perimeter is given by 4s, where s is the side length of the square.If the side length of a square is 4 inches, its area is __ square inches and its perimeter is __ inches.

Answer 1

Answer: Provided the side length which is 4in, and the formulas for both perimeter and the area, we have to evaluate each of the two:

$\begin{gathered} A=s^2\rightarrow1 \\ P=s\rightarrow2 \end{gathered}$

Area is:

$\begin{gathered} \begin{equation*} A=s^2 \end{equation*} \\ \therefore\rightarrow \\ A=(4in)^2 \\ A=4in\times4i\text{ }=16in^2 \\ A=16in^2 \end{gathered}$

Perimeter is:

$\begin{gathered} P=4s \\ P=4\times4=16 \\ P=16in \end{gathered}$
