I am in the same perdicament as you on this one. I found that one side is 18 and the other is 15, but I'm unable to find the algabraeic expression for it.
72 centimeters of what. im gonna assume the area is 72 cm. so it would be 72 sq cm your perimeter would be around 33.94 you need to take the squared root of 72. this gives the length of one side. then multiply this number by 4 since there are four sides to a square.
A pentagon has 5 sides. A regular pentagon has sides of all the same length. So a regular pentagon of side 5cm has a perimeter of 5 x 5cm = 25cm.
the perimeter is the sum of the length of every side of the geometrical figure. In your case, since you have 4 sides two of which are equal, the perimeter would be 2*(a+b) where a and b are the length of two sides
The perimeter is the length around something, add all sides together to get the length of the perimeter.
How many sides has a square? Are they all equal? Can you divide the perimeter by the number of sides?
The perimeter of a square with a side of length 4.76 centimeters is: (4 sides x 4.76) = 19.04 cm
Five times the length of one of the sides.
A square has sides of length 8.2 centimeters. What is the perimeter?
the perimeter is the sum of all the sides in a figure, and centimeter is a length. so the question is what is the sum of all the sides of a figure in centimeters
If a polygon with a perimeter of 30 centimeters has sides with length 6 cm/side, then it has 30 cm / 6 cm per side = 5 sides. So a regular pentagon with a side length of 6 cm has a perimeter of 30 centimeters.
387.5 centimeters (10 sides each the same length)
A rhombus has four sides that are equal in length, so the perimeter can be found by multiplying the length of one side by four. Therefore, a rhombus highway sign with a 20 centimeter side has a perimeter of 80 centimeters.
A regular pentagon has five sides of the same length. Therefore, the perimeter of the shape will be 8 x 5 = 40 centimetres.
The perimeter of a square is the sum of all its sides. In this case, if the perimeter is twenty centimeters, each side of the square would be five centimeters long.
30 cm. 2 sides are 9 cm and 2 sides are 6 cm (2x9)+(2x6)=? 18+12=30
A hexagon has six sides, and if it is regular then all the sides are the same length (in this case, 6cm). The perimeter is the total distance around the shape, so if each side if 6cm and there are six sides, then the perimeter will be 6x6cm, or 36cm.
The perimeter of a regular pentagon is five times the side length.
