Question: User: TL Michelle purchased a kid’s table with a square top. If the area of the square top is 400 square inches, what is the length of one of the sides?
Area =
400 in²
A square is shown in the top-left area of the page, with the label “Area = 400 in²” centered inside it.Teach me how to solve
1. **State the problem:** We need to find the length of one side of a square whose area is 400 square inches.
2. **Recall the formula for the area of a square:**
$$\text{Area} = \text{side}^2$$
This means the area is equal to the length of one side squared.
3. **Set up the equation using the given area:**
$$\text{side}^2 = 400$$
4. **Solve for the side length by taking the square root of both sides:**
$$\text{side} = \sqrt{400}$$
5. **Calculate the square root:**
$$\text{side} = 20$$
6. **Interpret the result:** The length of one side of the square is 20 inches.
**Final answer:**
$$\boxed{20 \text{ inches}}$$
