If you're talking about a five sided figure, just add up your figures.
The perimeter would be 8 + 9 + 10 = 27cm
18.5cmImproved Answer:-Perimeter = 9+9.5+9+9.5 = 37cm
24 cm is.
It would be 63cm. There are 7 sides and each side is 9cm so 7 times 9 is 63.
any 2-D shape could have a perimeter of 9cm. One example is a square with sides of 9/4 cm.
Perimeter = 6cm + 6cm + 9cm + 9cm = 30cm
ok if the perimeter is 36cm and it is a square then you know all four sides are equal 36cm / 4sides = 9cm for each side A = L * W ( both the length and width are 9cm because each side is equal ) A = 9cm * 9cm A = 81cm2
it is 81cm
9cm + 5cm + 9cm + 5cm = 28cm
Pentagon has 5 sides Regular => each side 9cm => perimeter = 5 x 9cm = 45cm
Area = (length of a side)2 = 81 square centimeters Perimeter = 4 x (length of a side) = 36 cm.
If you're talking about a five sided figure, just add up your figures.
9cm
The perimeter would be 8 + 9 + 10 = 27cm
28 cm
An arbitrary large number is the answer for anyrectangle, up to that with a length of 9cm, and 0cm as the width will have a perimeter of 18cm.Similarly, any rectangle up to that with sides 0cm long, and a width of 9cm will have your 18cm perimeter.
