Question

The perimeter, p, of a square is proportional to the length of one side, s. The equation representing this relationship is p = 4s. What is the perimeter of a square with a side length of 5 units?

1) 20 units
2) 25 units
3) 30 units
4) 35 units

Answer 1

The perimeter of a square with a side length of 5 units is 20 units.

Step-by-step explanation:

The perimeter of a square is calculated by adding up the lengths of all its sides. Since a square has 4 equal sides, the perimeter can be found by multiplying the length of one side, s, by 4. In this case, the equation representing the relationship between the perimeter and the side length is p = 4s.

To find the perimeter of a square with a side length of 5 units, substitute the value of s into the equation. p = 4(5) = 20 units.

Therefore, the perimeter of a square with a side length of 5 units is 20 units. The correct answer is option 1) 20 units.
