<p>Liam wants to lay tiles on his square kitchen floor of length 810 feet. The cost to lay a square foot of tile is 5 dollars. How much will it cost to tile the entire floor?</p>
56
<p>Okay, lets begin</p>
56
<p>Okay, lets begin</p>
57
<p>The length of the floor = 810 feet The cost to lay 1 square foot of tile = 5 dollars. To find the total cost to tile, we find the area of the floor, Area of the floor = area of the square = a² Here a = 810 Therefore, the area of the floor = 810² = 810 × 810 = 656,100. The cost to tile the floor = 656,100 × 5 = 3,280,500. The total cost = 3,280,500 dollars</p>
