Question

A wire of length 120 m is bent to form the following shapes. Find the length of each
side of all the shapes.
a) A regular pentagon c) Regular hexagon
b) Equilateral triangle d) Square

Answer 1

Answer:

its b or a

but i think its a

hope i answered correct

Answer 2

Answer:

a)Perimeter of regular pentagon=Length of the wire

5x side = 120 m

side= 120/5

Side of regular pentagon = 24 m

b)Perimeter of Equilateral triangle=Length of the wire

3x side = 120 m

side= 120/3

Side of Equilateral triangle = 40 m

c)Perimeter of regular hexagon=Length of the wire

6x side = 120 m

side= 120/6

Side of regular hexagon = 20 m

d)Perimeter of square=Length of the wire

4x side = 120 m

side= 120/4

Side of square= 30m
