A decagon has 10 sides. If it is a regular decagon, all of the sides are the same length.
Each side would be 0.8 yards or 2.4 feet in length.
None. 42 yards is a length with no width. Therefore it cannot have a perimeter.
The perimeter is the total distance around - width + width+ length + length.
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 is 300 yards. This is a length and is not measured in square feet which measure area. The area of this in square feet is 150 x 300 ie 45000 sq ft
The perimeter of a rectangle of dimensions 50 yards x 100 yards is 300 yards.
Perimeter = 4*4.8 = 19.2 yards
None. 42 yards is a length with no width. Therefore it cannot have a perimeter.
The perimeter is the total distance around - width + width+ length + length.
An octagon has 8 sides, thus the equation would be 8 x 7 = 56. So the perimeter would be 56 yards.
Length + width = half of perimeter so width = p/2 - length ie (22-12) 10 yards.
Perimeter = 5*8 = 40 yards
The rectangle would have two sides with 5 yards length and two sides with 3 yards of width, so you would have 5*2 + 3*2 = 10 + 6 = 16 yards.
20 yds
Since a square has four sides of equal length, divide the perimeter measurement by four: 300 / 4 = 75 yards.
65 yards
It is: 2*(9.5+4) = 27 yards
Suppose the length is y yards, then the perimeter is 2x + 2y = 6x + 6 yards so that 2y = 4x + 6 or y = 2x + 3 yards.
