Math help please?
Eric, Jose, Shannon, and Jackie wanted to plant a garden. Jose’s dad said they could use a
rectangular space in the backyard that was 8 m by 4 m.
The friends decided they would first like to make a colorful border for the garden using
small flowering plants called marigolds.
If they planted the marigold plants 10 cm apart, how many would they need to complete
the border?

I HAVE NO IDEA HOW TO DO THIS PROBLEM. PLease tell me what to do to more or less solve this, because this is very confusing.

    Let's first convert the meters to centimeters.

    8 m = 800 cm
    4 m = 400 cm

    The perimeter of the garden is:
    P = 2L + 2W
    P = 2(800) + 2(400)
    P = 2400 cm

    2400 / 10 = 240 plants
