Question

The perimeter of a square is defined by the function p(s)=4s if the perimeter is no more than 48 cm, which statement describes the domain for s, the side length of the square?

A. 0 < s ≤ 12
B. [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 ]
C. All real numbers
D. s ≤ 12​

Answer 1

• A. 0 < s ≤ 12

Explanation:

Given

• p(s) = 4s

If

• P ≤ 48

Then

• 4s ≤ 48
• s ≤ 12

Since perimeter can't be negative or zero, the domain will be:

• 0 < s ≤ 12

Correct choice is A
