Answer:

perimeter = 16
√(5) mm , area = 80 mm²

Explanation:

the sides of a square are congruent ( equal )

the perimeter (P) of a square is then calculated as

P = 4s ( s is the side length )

here s = 4
√(5) , then

P = 4 × 4
√(5) = 4 × 4 ×
√(5) = 16
√(5) mm

the area (A) of a square is calculated as

A = s² = ( 4
√(5) )² = 4² × (
√(5) )² = 16 × 5 = 80 mm²
