Question
14 mrs. drew wants to build a square sandbox with an area of 121 square feet. what is the total length of wood mrs. drew needs to make the sides of the sandbox?
Step1: Encontrar el lado del cuadrado
El área de un cuadrado es $A = s^{2}$, donde $s$ es el lado. Dado $A = 121$ pies², entonces $s=\sqrt{A}$.
$s=\sqrt{121}=11$ pies
Step2: Encontrar el perímetro del cuadrado
El perímetro de un cuadrado es $P = 4s$. Sustituyendo $s = 11$ pies, tenemos $P=4\times11$.
$P = 44$ pies
