Answer:
$204.85
Step-by-step explanation:
Let the two legs be the adjacent and the opposite of the right triangle. To get the third side (the hypotenuse), we will use the pythagoras theorem;
Perimeter of the garden will be the sum of all the three sides.
Perimeter of the garden = 12 + 12 + 16.97
Perimeter of the garden = 40.97 feet
Since 1 foot = $5
40.97 feet = x
Cross multiply
1*x = 5*40.97
x = 204.85
Hence it will cost $204.85 to fence the entire perimeter of the garden
