Question

A piece of wire is 90 cm long. What will be the length of each side if the string is used to
form:
a) A square.
b) A regular pentagon.
c) A regular hexagon.

Answer 1

Answer:

square =22.5 cm

regular Pentagon = 18cm

regular hexagon= 15cm

Step-by-step explanation:

Square has 4 sides

So we will divide 90 by 4 to get one side

=22.5cm

Pentagon has 5 sides

we will again divide it but with 5 to get one side

so 90/5

= 18cm

A regular hexagon has 6 sides

So we will divide 90 with 6

=15 cm
