Question

Each tile has an area of one sq ft. Ten sq ft of tile costs $8.00. The kitchen is 10ft wide and 14ft long. How much will be spent on tile?

Answer 1

Area of a rectangle is length times width, so:

10 x 14 = 140 square feet

You can get square tiles in groups of ten, so:

140 ÷ 10 = 14 groups

Each group costs $8, so:

14 x 8 = 112 dollars total
