• Time Remaining: 07:54:04

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?

7 square feet

This answer is correct. It is the calculation of the length times the width of the island.

8 square feet

This is the result of incorrectly multiplying the island's length by its height. The height of the island is not required in finding the area of the top.

9.5 square feet

This is the result of incorrectly finding the sum of all three dimensions of the island rather than calculating the area.

14 square feet

MY ANSWER

This is the result of incorrectly multiplying the island's width by its height. The height of the island is not required in finding the area of the top.
