the perimeter of a square can be expressed as 4(82) units. what is the length, in units, of a side of this square?
answer preview:

Explanation:

Step1: Recall perimeter formula

The perimeter $P$ of a square is $P = 4s$, where $s$ is the side - length of the square. Given $P=4(82)$.

Step2: Solve for side - length

Since $P = 4s$ and $P = 4(82)$, then $4s=4(82)$. Divide both sides by 4: $s=\frac{4\times82}{4}=82$.

Answer:

82
