BONJOUR,
✌ ✌ ✌ ✌


LENGHT OF WIRE = 60CM
SIDES IN REGULAR PENTAGON = 5

LENGHT OF EACH SIDE = 60/5
= 12 CM.

Answer 2

Solution :

It is given that , length of the

wire ( l ) = 60 cm

Let the length of the each side of

a pentagon = a cm

perimeter of the pentagon = length

of the wire

=> 4a = 60

=> a = 60/4

=> a = 15 cm

Therefore ,

length of the each side of the

pentagon = a = 15 cm
