JOHN is planting a garden. He wants to put a fence around it. If the garden is 3,000cm wide and 6,500 cm long, how much fence does he need? What will the cost be if fence is 15.25 per meter
3,000 cm = 30 m
6,500 cm = 65 m
P = 2L + 2W
P = 2(65) + 2(30)
Multiply the total perimeter by $15.25 to get the cost of the fencing.
thank you. 15.25 x 190
Right.
To calculate the amount of fence John needs, we need to find the perimeter of the garden. The perimeter of a rectangle can be found by adding up all of its sides.
The width of the garden is given as 3,000 cm, and the length is given as 6,500 cm. Since the fence is put around the entire garden, we need to calculate the perimeter using both the width and length.
Perimeter = 2 * (Width + Length)
Substituting the given values:
Perimeter = 2 * (3,000 + 6,500)
Now let's calculate the perimeter.
Perimeter = 2 * (9,500)
Perimeter = 19,000 cm
Since the cost of the fence is given as $15.25 per meter, we need to convert the perimeter from centimeters to meters.
1 meter = 100 cm
Perimeter in meters = Perimeter in centimeters / 100
Substituting the value of the perimeter:
Perimeter in meters = 19,000 / 100
Perimeter in meters = 190 m
Now let's calculate the cost of the fence.
Cost = Perimeter in meters * Cost per meter
Substituting the given values:
Cost = 190 * $15.25
Cost = $2,897.50
Therefore, John needs 19,000 cm of fence and it will cost $2,897.50.
