Question

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?
