Question

A square measures 6r centimeters on each side. Which monomial represents the area of the square?

Option 1: (6r)cm^2
Option 2: (6r^2)cm^2
Option 3: (36r)cm^2
Option 4: (36r^2)cm^2

Answer 1

Option 4

Explanation:

So we know that the area of a square is found by s^2. This means that we can just look for (6r)^2, since 6r is our side length! Let's see...We know that (6r)^2 is equal to 6^2 times r^2 because of the distributive property of exponents. Therefore, option 4 is our right answer. 36 is 6^2 and r^2 is r^2.
