Question

The area of a square is 16cm²
What is the perimeter?

Answer 1

16

Explanation:

Square root of 16 = 4cm

4 sides, 4 * 4 = 16cm

Answer 2

Perimeter = 16 cm

Explanation:

The formula for a square's area = s^2 where the length of the side is s.

s^2 = 16 Take the square root of both sides

sqrt(s^2) = sqrt(16)

s = 4

The perimeter is the same

P = 4*s

P = 4 * 4

P = 16
