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
THANK YOU SO MUCH !!!!!!!!
You're very welcome!
To solve this problem, you need to find the perimeter of the rectangular garden and then calculate the number of marigold plants needed to complete the border.
Step 1: Find the perimeter of the rectangular garden.
The perimeter of a rectangle is calculated by adding all four sides together.
Perimeter = 2(length + width)
Given that the length is 8 meters and the width is 4 meters:
Perimeter = 2(8 + 4) = 2(12) = 24 meters.
Step 2: Convert the perimeter to centimeters.
Since the distance between the marigold plants is given in centimeters, it is necessary to convert the perimeter from meters to centimeters. Recall that 1 meter is equal to 100 centimeters.
Perimeter in centimeters = Perimeter in meters * 100
Perimeter in centimeters = 24 meters * 100 = 2400 centimeters.
Step 3: Calculate the number of marigold plants needed.
The marigold plants are to be planted 10 cm apart. To find the number of plants needed, divide the perimeter in centimeters by the distance between plants.
Number of plants needed = Perimeter in centimeters / Distance between plants
Number of plants needed = 2400 centimeters / 10 centimeters = 240 plants.
Therefore, to complete the border, Eric, Jose, Shannon, and Jackie would need to plant 240 marigold plants.
