A triangular flower bed (space for planting flowers) needs a thin metal border all the way around it. The sides are 7 feet, 6 feet, and 9 feet long. Homework Help ✎
How many feet of border should be purchased? Make a sketch and show your work.
This problem is asking you to find the perimeter (distance around) the flower bed.
In order to cover the perimeter, 22 feet of border should be purchased.
Begin by sketching a picture of the flower bed with labels.
Add the lengths of the sides to find the perimeter.
7 feet + 6 feet + 9 feet = 22 feet
If borders cost $8.75 per yard (and only whole numbers of yards can be purchased), how much would the border cost?
Remember to convert the length of border to yards before finding the cost.
