Question

question 2.
given the area of a square, which mathematical operation is required to find the length of the side of the square?
a. addition
b. subtraction
c. cube root
d. square root

Explanation:

The area \( A \) of a square with side length \( s \) is given by the formula \( A = s^2 \). To find the side length \( s \) when the area \( A \) is known, we need to reverse the squaring operation. The inverse operation of squaring a number is taking its square root. So, \( s=\sqrt{A} \). Addition and subtraction are not related to finding the side from the area of a square. The cube root is used for finding the side of a cube from its volume (where \( V = s^3 \)), not for a square.

Answer:

D. square root
