calculation of the area of the marble rectangle

 A homeowner wants to install a new marble countertop on their kitchen island. They take measurements of the island and find that the length is 2 feet, the width is 3.5 feet and the height of the island is 4 feet. Which of the following is the correct calculation of the area of the marble rectangle they need to cover the top of the island, without any overhang?

Here’s how to figure it out, step by step:

1. Identify what you’re covering: the top of the island, which is a rectangle.

2. Use the rectangle area formula:
   Area = length × width
   (Height is irrelevant for top surface area.)

3. Plug in the measurements (in feet):
   Area = 2 ft × 3.5 ft

4. Multiply:
   Area = 7 square feet

So, the correct calculation is 2 × 3.5 = 7 ft² (no overhang).

Quick check in inches (optional): 2 ft = 24 in, 3.5 ft = 42 in → 24 × 42 = 1008 in² → 1008 ÷ 144 = 7 ft².
