To find the perimeter of a regular pentagon with 9cm sides, you would multiply the length of one side by the total number of sides. In this case, 9cm x 5 sides = 45cm. Therefore, the perimeter of a regular pentagon with 9cm sides is 45cm.
any 2-D shape could have a perimeter of 9cm. One example is a square with sides of 9/4 cm.
Area 51.
This is not an equilateral triangle.
No. The sum of the lengths of any two sides of a triangle must be greater that the third. Here 6 + 9 = 15, not > 15.
Assuming no fractional dimensions, least possible area would be a rectangle measuring 1cm x 9cm. Area increases to a maximum of 25 sq cm when shape is square, ie 5cm x 5cm.
Perimeter = sum of the lengths of sides = 5* 7 cm = 35 cm
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
Well, honey, making a shape with a perimeter of 9cm is as easy as pie. You could have a triangle with sides measuring 3cm, 3cm, and 3cm. Or you could have a rectangle with sides measuring 2cm and 2.5cm. Just remember, the perimeter is the sum of all the sides, so get those measuring tapes out and get creative!
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.
it is 81cm
9cm + 5cm + 9cm + 5cm = 28cm
if you have a box that is 9cm long and 3cm wide then you would say width + length + width + length because the side opposite from 3cm is also 3cm and the side opposite 9cm is also 9cm. so you would add: 9cm+9cm+3cm+3cm = 24cm if you have a box that is 9cm long and 3cm wide then you would say width + length + width + length because the side opposite from 3cm is also 3cm and the side opposite 9cm is also 9cm. so you would add: 9cm+9cm+3cm+3cm = 24cm
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
To draw a shape with a 9cm perimeter, you can create a triangle, square, or rectangle. For a triangle, you could have sides measuring 3cm, 3cm, and 3cm. For a square, all four sides would be 2.25cm. For a rectangle, two sides could be 2cm and the other two sides could be 2.5cm. These shapes will all have a perimeter of 9cm.
All you do is add the sides up for the perimeter. 12 + 10 + 9 = 31
