Question

$\text{The dimensions of a rectangular plot}$ $\text{of land are 4 mi and 1 mi, respectively.}$
$\text{Find the cost of fencing the plot at the}$ $\text{rate of}\$\text{3 per yd.}$

• A. $528,00
• B. $480,00
• C. $614,00
• D. $497,00

Answer 1

The correct option is A $528,00

$\text{We have to find the cost of fencing}$
$\text{the rectangular plot.}$

$\text{Length (l) = 4 mi}$
$\text{Width (w) = 2 mi}$

$\text{Let's find the perimeter first.}$


$\text{The perimeter of the given region}$ $\text{is 10 mi.}$

$\text{It is given that the cost of fencing}$ $\text{1 yd is}\$3\text{.}$

$\text{So, let's convert the perimeter into}$ $\text{yd.}$

$\text{We know that,}$
$\text{1 mi =}$ $\text{1760 yd}$


$\text{Hence, multiply 10 with 1760.}$

$\text{So, 10 mi}=10\times 1\text{mi}$
$=10\times 1760\text{yd}$
$=17600\text{yd}$

$\text{Now, let's calculate the cost of}$ $\text{fencing.}$


$\text{Therefore, the total cost of fencing}$ $\text{is}\$\text{52,800.}$
