Question 46·Easy·Area and Volume
A rectangle has a length of 12 centimeters and a width of 5 centimeters. What is the area, in square centimeters, of the rectangle?
For rectangle area questions, quickly recall that area equals length times width, making sure you are not mistakenly finding perimeter. Multiply the two given side lengths directly, watch your basic arithmetic, and confirm that your final answer is in square units (e.g., square centimeters) and matches one of the choices.
Hints
Identify what is being asked
The question is asking for the area of a rectangle, not its perimeter. Think about which formula you use for area.
Recall the correct formula
For a rectangle, area is found by multiplying two measurements. Which two sides of a rectangle do you use?
Use the given dimensions
You are told the length is 12 centimeters and the width is 5 centimeters. Plug these into the area formula and then simplify the multiplication.
Desmos Guide
Use Desmos to compute the product
In the Desmos calculator, type 12*5 and press Enter. The value that Desmos outputs is the area of the rectangle in square centimeters; match that value to the correct answer choice.
Step-by-step Explanation
Recall the area formula for a rectangle
The area of a rectangle is found by multiplying its length by its width :
In this problem, the length is 12 centimeters and the width is 5 centimeters.
Substitute the given values into the formula
Replace with 12 and with 5 in the formula:
Now you just need to compute this product.
Multiply to find the area and choose the matching option
Calculate the product:
So, the area of the rectangle is 60 square centimeters, which corresponds to answer choice C.
