Question

Mariah is setting tile on the floors of her rectangular kitchen and square breakfast area.the diagram shows the dimensions of the 2 rooms. Each tile covers 1 square foot.if each tile cost $1.29, how much will Mariah pay to buy tile for both rooms?

Answer 1

at first,

area of breakfast area,

`= {10}^(2)`

`= 100 {ft}^(2)`

area of kitchen,

`= 10 * 14`

`= 140 {ft}^(2)`

now, total area,

`= 100 + 140`

`= 240 {ft}^(2)`

rate per square ft = $ 1.29

total cost ,

`= 240 * 1.29`

= $ 309.60

answer is B.
