Answer:
Explanation:
The cost of a patio is likely proportional to its area. So, we can calculate the cost per square foot for the 15 ft by 20 ft patio and then use that to estimate the cost of the 16 ft by 24 ft patio.
First, let's calculate the area of the 15 ft by 20 ft patio:
Area = length x width = 15 ft x 20 ft = 300 sq ft
The cost per square foot is then $2275 / 300 sq ft = $7.58 per sq ft (rounded to the nearest cent).
Next, let's calculate the area of the 16 ft by 24 ft patio:
Area = length x width = 16 ft x 24 ft = 384 sq ft
So, the estimated cost of the 16 ft by 24 ft patio would be:
Cost = area x cost per square foot = 384 sq ft x $7.58 per sq ft = $2911.52
So, a 16 ft by 24 ft patio would cost approximately $2911.52 to install, assuming the cost per square foot remains constant.
