Question

Gridded Response Find the area (in square inches) of a square with a side length of 12 inches.

Short answer

The area of square is $144\text{square inches}$.

Step-by-step solution

Step-1 – Area of square

The area of a square with side length x is given by the formula

$\begin{array}{c}\text{Areaofsquare}={\left(\text{side}\right)}^2\\ A=x^2\end{array}$

Step-2 – Given

The length of the given square is 12 inches.

We need to find the area of the square.

So, substitute the value of side length in above formula of area of square and evaluate further by multiplying.

Step-3 – Find the area of square

In order to evaluate the area of the square, substitute 12 for x in above area formula and simplify further as shown below by expanding the exponent

$\begin{array}{c}\text{Areaofsquare}={\left(\text{side}\right)}^2\\ ={\left(12\right)}^2\\ =12\cdot 12\\ =144\end{array}$

Thus, the area of square is $144\text{square inches}$.
