Lionel's front yard is in the shape of a square and has an area of 225 square meters. What is the length in meters of one side of Lionel's front yard?A) 112.5B) 56.25C) 25D) 15

Respuesta :

The area of a square is given by the formula:

[tex]A=l^2[/tex]

Where l is the length of its side. If the area is given, then the length can be calculated from that formula taking the square root to both sides of the equation. Then:

[tex]l=\sqrt[]{A}[/tex]

Substitute A=225 to find the length of the square:

[tex]\begin{gathered} l=\sqrt[]{225} \\ \Rightarrow l=15 \end{gathered}[/tex]
