An aluminium wire in the shape of a square has a perimeter of 60cm what is the length of each side of the square? If the wire is regent into a regular Pentagon then find the length of each side

If the wire is in the shape of square,

that means length of all the 4 sides will be equal.

Perimeter of a square is the sum of all the 4 sides = 60cm

Length of each side = 60/4 = 15 cm

 

If the same wire is bent to a regular pentagon,

the perimeter will remain the same.

 

A regular pentagon has 5 sides of equal length,

thus, the length of each side will be

60 / 5 = 12 cm
