iii)a regular pentagon if the perimeter is 45cm.​

Answer 1

Answer:

the perimeter of square is 4 * side

so

it's side is equal to 32/4 which is 8

perimeter of equilateral triangle is equal to side plus side plus side so

its one side is equal to

18/3 which is equal to 6

Answer 2

Answer:

1)8cm

2)6cm

3)9cm

Step-by-step explanation:

1)perimeter of square/4=each side.so 32 cm/4=8cm

2)perimeter of equi triangle/3=eaxh side.so 18cm/3=6cm

3)perimeter of reg pentagom/5=each side.so 45cm/5=9cm
