Answer:
A. 191.54 ft²
B. $2011.17
Explanation:
Part A involves multiplying to find the area of the living room using the formula to find the area of a rectangle.
A = b*h (original formula)
A = 15.7*12.2 (substitute values)
A = 191.54 (multiply)
The area of his living room is 191.54 ft²
Next, you need to multiply the number of ft² by the cost per ft² to find the cost to tile the living room
Cost = $10.50*191.54 (equation)
Cost = $2011.17 (multiply)
The total cost of tiling the living room would be $2011.17
