Find the perimeter of the following trapezoid:<br> 6 ft<br> 2.5 ft/ 12 ft<br> 2.5 ft<br> 8 ft
sasho [114]

Answer:

31ft

Step-by-step explanation:

6 ft  + 2.5 ft + 12 ft  + 2.5 ft  + 8 ft  = 31ft

I assumed the slash in the space between 2.5ft and 12ft was an error, so I ignored it in the solution to this problem.

Besides that, perimeter is found by adding all sides of the shape or figure together, and the sum of that is the perimeter.

The basic formula for perimeter is:

base + height + base + height.

I do not think you square perimeter as you do area (e.g. 31ft^2).
