Answer 1

The perimeter of the square is option E. 16√5 mm.

The area of the square is option A. 80 mm².

Explanation:

1. Let's calculate the perimeter of this square:

The perimeter of a square is the sum of its side 4 times, thus:

Perimeter = 4√5 + 4√5 + 4√5 + 4√5

Perimeter = 16 √5

Perimeter = 4 * 4√5 = 16√5

The correct answer is option E. 16√5 mm

2. Let's calculate the area of this square:

The area of a square is the length of its side squared, thus:

Area = (4√5)²

Area = 4√5 * 4√5

Area = (4 * 4 * √5 * √5)

Area = 16 * 5 = 80

The correct answer is A. 80 mm²
