Answer:
4 and 16 units²
Step-by-step explanation:
The perimeter of a square of side s = 4s and area = s² , equating gives
s² = 4s ( subtract 4s from both sides )
s² - 4s = 0 ( factor out s from each term on the left )
s(s - 4) = 0
Equate each factor to zero and solve for s
s = 0
s - 4 = 0 ⇒ s = 4
However, s > 0, thus s= 4
That is side = 4 units and area = 4² = 16 units²
