I have a rectangle shaped garden with the longer side measuring 14 m and the smaller side measuring 10m. I want to put brick path around the outside with bricks that are 50cm wide. How many bricks will i need?
the long side is 28 bricks, and the short side is 20 bricks.
You will need 2(28+10)+4 bricks.
Why the extra 4?
To find out how many bricks you will need for the path around the garden, you need to calculate the perimeter of the garden.
The perimeter of a rectangle is given by the formula:
Perimeter = 2 * (Length + Width)
In this case, the longer side (Length) is 14 m, and the smaller side (Width) is 10 m.
So, the perimeter of your garden is:
Perimeter = 2 * (14 m + 10 m)
Perimeter = 2 * 24 m
Perimeter = 48 m
Since the bricks are 50 cm wide, we need to convert the perimeter of the garden to centimeters as well.
To convert meters to centimeters, you need to multiply by 100, since there are 100 centimeters in 1 meter.
Perimeter in centimeters = 48 m * 100 cm/m
Perimeter in centimeters = 4800 cm
Now, we can find out how many bricks will be needed for the path. Divide the perimeter of the garden by the width of each brick (50 cm):
Number of bricks = Perimeter in centimeters / Width of each brick
Number of bricks = 4800 cm / 50 cm
Number of bricks = 96
Therefore, you will need 96 bricks to create a path around your garden.
