Question

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, 9 feet long. How many feet of the border should be purchased?

Answer 1

To find the total length of the border needed for the triangular flower bed, add the lengths of all three sides.

Step-by-step explanation:

To find the total length of the border needed for the triangular flower bed, we need to add the lengths of all three sides. The lengths of the sides are 7 feet, 6 feet, and 9 feet. So, the total length of the border to be purchased is 7 + 6 + 9 = 22 feet.

Answer 2

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
