One hundred forty-eight ceramic tiles are required to tile a 25-square-foot area. At this rate, how many tiles are required to tile 250 ft2?

Answer 1

250 = 10 times 25

you need 10 times as many tiles

148 x 10 = 1480 tiles for 250 square feet

Answer 2

With any problem, we always want to start with what we know.

We know that 148 tiles are required to cover a 25ft² area.

Then you can move to what you want to find out.

We want to find out how many tiles are required to cover a 250ft² area.

From this, we can set a relationship. Since how much the tiles can cover isn't changing we can use this to find the number of tiles needed.

number of tiles = number of tiles

area area

Introduce numbers and variable (x=number of tiles needed)

148 tiles = x

25ft² 250ft²

Solve for x

x= (148 tiles)(250ft²) =1480 tiles

25ft²
