perimeter of a regular pentagon with side measurements of 57 centimeters
Bran...
Perimeter=all sides added up.
Pentagon=5 sided
Each Side=57 cm
57x5=?
285 Centimeters
Doesn't a regular pentagon have 5 equal sides?
And isn't one of those equal sides equal 57 cm?
And isn't 'perimeter' all the way around?
Ahh, the quandary
Find the perimeter of a regular pentagon with a side measure of 57 centimeters.
A. 285 cm B. 649 cm
C. 228 cm D. 342 cm
285 cm
A regular pentagon has five equal sides, so if each side measures 57 centimeters, we can calculate the perimeter by multiplying the side length by 5:
Perimeter = 57 cm * 5 = 285 cm
So, the perimeter of a regular pentagon with side measurements of 57 centimeters is 285 centimeters. That's enough to make any pentagon look like it's running a marathon!
To find the perimeter of a regular pentagon, you need to know the length of one side. In this case, you provided the side measurement of 57 centimeters.
The formula for the perimeter of a regular pentagon is:
Perimeter = 5 * Side Length
Substituting the given side length into the formula:
Perimeter = 5 * 57 centimeters
Evaluating the equation:
Perimeter = 285 centimeters
Therefore, the perimeter of a regular pentagon with side measurements of 57 centimeters is 285 centimeters.
