Answer 1

The area of the rectangular barn door is calculated by multiplying its height (80 inches) by its width (60 inches), resulting in 4,800 square inches, which is option A.

Step-by-step explanation:

To find the area of a rectangular surface, you multiply the height by the width. In this case, the door is 80 inches high and 60 inches wide. Therefore, the area of the outside of the door can be calculated by multiplying these two dimensions.

Area = height × width = 80 inches × 60 inches = 4,800 square inches.

So, the correct answer to the dimension of the area of the door is:

A) 4,800 in².
