Question

If the tile cost 1.29 how much will Mariel pay to buy tiles for both rooms

Answer 1

Given:

• The side of the square breakfast area is a=10ft.

,

• The length of the rectangular kitchen is l=10 ft.

,

• The breadth of the rectangular kitchen is b=14 ft.

,

• The area of the tile is 1 square foot.

To find the total tile cost when each tile costs $1.29:

First, we need to find the number of tiles required.

So, the formula is

`\begin{gathered} n=\frac{\text{Area of the square breakfast area + Area of the rectangular kitchen }}{\text{Area of the tile}} \\ =(a^2+lb)/(1) \\ =(10^2+(10)(14))/(1) \\ =100+140 \\ =240\text{ tiles.} \end{gathered}`

Next, to find the total tile cost.

The formula is,

`\begin{gathered} \text{Total cost=Number of tiles}*\cos t\text{ of a tile} \\ =240*1.29 \\ =309.6 \end{gathered}`

Therefore, the total cost to buy the required number of tiles is $309.6
