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

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
[tex]\begin{gathered} n=\frac{\text{Area of the square breakfast area + Area of the rectangular kitchen }}{\text{Area of the tile}} \\ =\frac{a^2+lb}{1} \\ =\frac{10^2+(10)(14)}{1} \\ =100+140 \\ =240\text{ tiles.} \end{gathered}[/tex]Next, to find the total tile cost.
The formula is,
[tex]\begin{gathered} \text{Total cost=Number of tiles}\times\cos t\text{ of a tile} \\ =240\times1.29 \\ =309.6 \end{gathered}[/tex]Therefore, the total cost to buy the required number of tiles is $309.6
