The perimeter and area of the square are 16√5 mm and 80 mm²
<h3 /><h3>How to find perimeter and area of a square?</h3>
Perimeter of a square = 4L
where
Therefore,
Perimeter of a square = 4 × 4√5
Perimeter of a square = 16√5 mm
Area of a square = l²
Area of a square = (4√5)²
Area of a square = 16 × 5
Area of a square = 80 mm²
