Answer:
A = m²
Step-by-step explanation:
Given that a square has a perimeter of (2x - 48),
Each side of the perimeter must be: (because a square has 4 sides)
We need to determine the side of each perimeter:
s =
Factor out 2 from the numerator:
s =
Then, cancel out 2 and 4 from the fraction, leaving 2 in the denominator:
s = ← <em><u>This represents the side of a square</u></em>
Therefore, the area of a square is:
A = side (s)²
A = m²
