George wants to fence his square garden, which has a side of 20 feet, with two rows of bulb wire. The store sold bulb wire by te meter at 12/meter.How much does george need to buy the bulb wire needed to fence his garden?
area = 400feet
covert feet^2 to meter^2= 37.16m^2
if you want money how much you have to spent then multiply by 12
To find out how much bulb wire George needs to buy, we first need to calculate the perimeter of his square garden.
The perimeter of a square is given by the formula: P = 4s, where P represents the perimeter and s represents the side length of the square.
In this case, George's garden has a side length of 20 feet, so we can substitute s = 20 into the formula:
P = 4 * 20 = 80 feet.
Now, George wants to use two rows of bulb wire, so we need to multiply the perimeter by 2 to account for both rows:
Total wire needed = 80 feet * 2 = 160 feet.
Since the bulb wire is sold by the meter, we need to calculate the equivalent length in meters.
1 foot is approximately equal to 0.3048 meters.
Therefore, the total wire needed in meters is:
160 feet * 0.3048 meters/foot = 48.768 meters.
Now, we can calculate the cost of the bulb wire. Given that the wire is sold at a rate of 12 dollars per meter, we can multiply the total wire needed by the cost per meter to find the total cost:
Total cost = 48.768 meters * 12 dollars/meter = 585.216 dollars.
So, George needs to buy approximately 48.768 meters of bulb wire, which will cost him approximately 585.216 dollars.
