Question

The dimensions of a plot are $13.2\text{feet}\times 14.5\text{feet}$. If the cost of the plot per square foot is $\$0.25$, find the total cost of the plot.

• A. $\$47.85$
• B. $\$478.5$
• C. $\$49.18$
• D. $\$51.04$

Answer 1

The correct option is A $\$47.85$

First, let’s find the area of the plot.
Area of the plot $=(13.2\times 14.5)sqft$


Since there are two decimal places in both $13.2$ and $14.5$, we will add a decimal point two places from the right in the final answer.

Total area of the plot $=191.40sqft$
Cost of the plot per $sqft=\$0.25$
To find the total cost of the plot, we multiply the cost per sq ft by the total area of the plot.
Total cost $=\$(191.4\times 0.25)$


Since the total number of decimal places in $191.4$ and $0.25$ is three, we will add the decimal point 3 places from the right in the final answer.

Therefore, the total cost is $\$\mathrm{47.85.}$
