A square bedroom has an area of 100 square feet. How long is each side? _____ feet

Identify Area Equation: Let s be the side length of the square. Which equation represents the area of a square. The area is the product of the lengths of two sides. A = s^2Substitute Area Value: Area of square bedroom: 100 square feet Which equation represents the area of a square bedroom. Substitute 100 for A in A = s^2. 100 = s^2Solve for Side Length: 100 = s^2 What is the length of each side of the bedroom? Take the square root of both sides to solve for s. sqrt(100) = sqrt(s^2) 10 = s Side length of the square bedroom: 10 feet

Identify Area Equation: Let $s$ be the side length of the square. $\newline$ Which equation represents the area of a square. $\newline$ The area is the product of the lengths of two sides. $\newline$ $A = s^2$
Substitute Area Value: Area of square bedroom: $100$ square feet $\newline$ Which equation represents the area of a square bedroom. $\newline$ Substitute $100$ for $A$ in $A = s^2$ . $\newline$ $100 = s^2$
Solve for Side Length: $100 = s^2$ $\newline$ What is the length of each side of the bedroom? $\newline$ Take the square root of both sides to solve for $s$ . $\newline$ $\sqrt{100} = \sqrt{s^2}$ $\newline$ $10 = s$ $\newline$ Side length of the square bedroom: $10$ feet
