The perimeters of the square and the regular pentagon are equal. A square with side lengths of 3x + 3. A pentagon with side lengths of x + 8.

60

Step-by-step explanation:

Since the perimeters are equal then:

(3x + 3) * 4 = (x + 8) * 5

12x + 12 = 5x + 40

7x = 28

x =4

Perimeter of square = (3*4 + 3) * 4 =

(12 + 3) * 4 = 60

Perimeter of pentagon = (4 + 8) * 5 =

(12) * 5 = 60

The answer is 60
