Question

CAMPING The square floor of a tent has an area of 49 square feet. What is the side length of the tent?

Step-by-Step Solution

Answer

The side length of the tent is 7 feet.

Step 1. State the formula.

The formula of area of a square is $A=s^2$, where A is the area and s is the side length of the square. Thus, the formula of the side length of a square, from its area is $s=\sqrt{A}$.

Step 2. List the given data.

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

Step 3. Calculate the side length.

Put $A=49$ in $s=\sqrt{A}$ to get,

$$\begin{gathered} s=\sqrt{49} \\ =7 \end{gathered}$$ 

So, $s=7$

Step 4. Determine the unit.

Since the area of the square is given as square feet, the unit of the side length, which is just the square root of the area is feet.

 

So, the side length of the tent is 7 feet.
