Compute the number of vinyl tiles, measuring 10 in. each side, needed to tile a kitchen measuring 20 ft. by 16 ft.

461 tiles (Approx) vinyl tiles are used in kichen tile .

Step-by-step explanation:

Formula

Area of a rectangle = Length × Breadth

As given

A tile  kitchen measuring 20 ft. by 16 ft.

Here Length = 20 ft

Breadth = 16 ft

Put in the formula

Area of a kitchen tile = 20 × 16

                                  = 320 ft²

As 1foot = 12 inches

Thus

Convert 320 ft² into inches² .

320 ft² = 320 × 12 × 12 inches²

            = 46080 inches²

As given

The number of vinyl tiles, measuring 10 in.

Area of a square = a²

Where a is the side of a square .

Thus

Area of a vinyl tiles = 10 × 10

                       = 100 inches²

Let us assume that the number of vinyl tiles be x.

Than

x ×  Area of a vinyl tiles = Area of a kitchen tile

Put in the formula

x × 100 = 46080

x = 460.8 tiles

x = 461 (Approx) tiles

Therefore  461 tiles (Approx) vinyl tiles are used in kichen tile .
