Answer 1

Answer: 22 feets of the border should be purchased

Step-by-step explanation:

A triangular flower bed (space for planting flowers) needs a thin metal border all the way around it. We want to look for the number of feet of the border that should be purchased. In this case, we are dealing with the distance round the border which is a triangle. The distance round the border is also known as the perimeter of the border. Therefore,

The perimeter of a triangle is the sum of all three sides.

The dimension of the sides are given as 7 feet, 6 feet, 9 feet long. Therefore, the perimeter is

7 + 6 + 9 = 22 feets
