Pentagon has 5 sides Regular => each side 9cm => perimeter = 5 x 9cm = 45cm
Perimeter = 6cm + 6cm + 9cm + 9cm = 30cm
9cm + 5cm + 9cm + 5cm = 28cm
63 cmPerimeter = 2 x (Length + Width) = 2 x (9cm + 7cm) = 2 x 16cm = 32cm
If you're talking about a five sided figure, just add up your figures.
any 2-D shape could have a perimeter of 9cm. One example is a square with sides of 9/4 cm.
19 cm x 9cm x 9cm.
The perimeter would be 8 + 9 + 10 = 27cm
18.5cmImproved Answer:-Perimeter = 9+9.5+9+9.5 = 37cm
Area = (length of a side)2 = 81 square centimeters Perimeter = 4 x (length of a side) = 36 cm.
