Question:

Tiling costs $2.89 per square foot. What is the cost to tile a kitchen whose dimensions are 4 yards by 5 yards?

A $520.20
Explaination

There are 3 feet in a yard, so a kitchen 4 yards by 5 yards is equivalent to (4 × 3) feet by (5 × 3) feet, or 12 feet by 15 feet. The area of the kitchen is 12 × 15 = 180 square feet. The cost to tile is $2.89 × 180 = $520.20.
