Chapter 0.8, Problem 17E

To determine

To calculate: The side length of the square floor of tent.

Answer to Problem 17E

The side length of the square floor of tent is $\text{7 feet}$ .

Explanation of Solution

Given information:

The square floor of a tent has an area of $49$ square feet.

Formula used:

Area $\left(A\right)$ of square is square of its side. Let side of the square be of length $\left(l\right)$ . It is mathematically denoted by $A=l^2$ .

Calculation:

Consider the provided statement that the area of square floor of the tent has an area of $49$ square feet.

Recall that area $\left(A\right)$ of square is square of its side. Let side of the square be of length $\left(l\right)$ . It is mathematically denoted by $A=l^2$ .

Apply it,

  $\begin{array}{c}A=l^2\\ 49=l^2\end{array}$

Taking square root both sides, we get,

  $\begin{array}{c}{7}^2=l^2\\ 7=l\end{array}$

Thus, the side length of square floor of tent is 7 feet.
