The perimeter of a regular pentagon is 1540 cm. How long is its each side?

Answer:

Given, that perimeter of regular pentagon = 1540 cm. \[\because \] Perimeter of regular pentagon \[=5\times \] length of its side                                                                                                       [\[\because \] pentagon has 5 sides of equal length]       \[1540=5\times \] length of its side \[\therefore \] length of its side \[=\frac{1540}{5}=308\] Hence, the length of each side is 308 cm.
