A pentagon has 5 sides
5 1/8 cm x 5 = ?
To find the perimeter of any polygon, including a regular pentagon, you need to add up the lengths of all its sides.
In this case, we are given that one side of the pentagon measures 5 1/8 cm. To find the perimeter, we need to multiply this length by the number of sides in the pentagon.
A regular pentagon has 5 sides of equal length. Therefore, to find the perimeter, we multiply the length of one side by 5.
Let's first convert the mixed number 5 1/8 into an improper fraction.
5 1/8 = (5 * 8 + 1)/8 = 41/8
Now we can calculate the perimeter of the pentagon:
Perimeter = (Side length) * (Number of sides)
= (41/8 cm) * 5
= 205/8 cm
To simplify the answer, we can express it as a mixed number:
205/8 = 25 5/8 cm
Hence, the perimeter of the regular pentagon is 25 5/8 cm.
