A pentagon is a 5-sided figure, and the perimeter is the sum of the lengths of all the sides. A pentagon with 15-inch sides, will have 5 x 15 inches = 75 inches as its perimeter.
15 x 4 = 60 inches
A regular pentagon has a perimeter of 5s. We set this equal to 15, and solve for s, and convert to yards.5s = 15s = 33 feet converted to yards is 3/3 = 1 yard.
Perimeter = 8*15 = 120 cm
2.5ins, 6ins and 6.5ins respectively.The perimeter of a 5-12-13 triangle would be 30 in.The shortest side is 5/30 = 1/6 of the perimeter, the middle side is 12/30 = 2/5 and the biggest is 13/30.So, for the triangle with perimeter 15 inches, the smallest side is 1/6*15 = 2.5 inches.The middle side is 2/5*15 = 6 inches and the biggest side is 13/30*15 = 6.5 inches.
wire is first bent into the shape of a triangle. Each side of the triangle is 16 cm long. Then the wire is unbent and reshaped into a rectangle. If the length of the rectangle is 17 cm, what is its width?
The perimeter of a triangle is the sum of the lengths of its sides. In this case, the perimeter of the triangle with sides measuring 3 inches, 5 inches, and 7 inches is 3 + 5 + 7 = 15 inches.
5t+15
15 ft.
15" x 4 sides = 60-inch perimeter.
15 x 4 = 60 inches
4 sides x 15 in./side = 60 inches.
The perimeter is the sum of all sides. An equilateral triangle has three sides of equal length. So if one side is 5 inches, and we have three of these, we get a perimeter of 15 inches.
A square has four equal sides. If its perimeter is 60 inches, then each side is 15 inches. A 15x15 square has an area of 15x15 = 225 square inches.
A pentagon has 5 sides.A regular pentagon has every side the same length.Perimeter = 5 x 3s= 15 s(whatever unit a s is, other than a second.)
15 sides
15 cm * 6 sides = 90 cm perimeter
You would get the number 15 because a pentagon has 5 sides and a decagon has 10 sides. 10+5=15. Your answer would be 15 sides.
