Question

If the perimeter of a regular pentagon is 55x*y* + 35x"y - 5xy, what is the length of

each side? Find the length if x = 4.
Formula: P= 5S

Answer 1

The formula for finding the side length of a regular pentagon is P = 5S, where P is the perimeter and S is the side length. In this case, the perimeter of the regular pentagon is given as 55x*y* + 35x"y - 5xy. If we set x = 4, then the perimeter equals 203, so S = 203/5 = 40.6. Therefore, the length of each side of the regular pentagon is 40.6 when x = 4.
