L + W = P/2 ie 30 cm, so Length = 30 - Width, but you haven't given enough info.
subtract the two sides that you know from the perimeter to get the unknown side.
if you have the length of one side - plus the perimeter... Divide the perimeter by 2, then subtract the known side - this leaves you with the unknown dimension. For example... Say you have a side length of 10, and a perimeter of 30. 30/2 = 15, subtract 10 from that - and you get the missing measurement of 5.
You begin by finding the length of the unknown side. The square of the hypotenuse is equal to the sum of the squares of the two legs. Then once you have the lengths of all 3 sides, you adum all up, and you have the perimeter.
Perimeter of a triangle = (length of side #1) + (length of side #2) + (length of side #3)
Side length: 6.02x Perimeter: 19.6x
If the hexagon isn't regular, then the formula is: Perimeter = (side-1 length)+(side-2 length)+(side-3 length)+(side-4 length)+(side 5 length)+(side-6 length) If the hexagon is regular, then the formula is: Perimeter = 6 x (length of any side)
The perimeter of a triangle is the sum of its 3 sides.
Perimeter = Length of side 1 + Length of side 2 + Length of side 3 + Length of side 4 + Length of side 5 + Length of side 6 + Length of side 7 + Length of side 8.
Perimeter of a triangle = (length of the first side) plus (length of the second side) plus (length of the third side)
Perimeter of a triangle = (length of the first side) plus (length of the second side) plus (length of the third side)
No. Perimeter = side + side + side + side. (However many sides there are.) Area = length x width
The perimeter of a square is 400 meters. write an equation for the perimeter and solve for the length of one side
