Answer 1

Solution

If the wire is used to make a regular pentagon

Perimeter of regular pentagon

=

78

m

Let the side of regular pentagon be

x

m

Then,

5

x

=

78

x

=

15.6

m

If the wire is used to make regular hexagon

Perimeter of regular hexagon

=

78

m

Let the side of regular hexagon be

y

m

Then,

6

y

=

78

y

=

13

m

Therefore difference in the lengths of its sides

=

15.6

−

13

=

2.6

m
