A triangular sail has a perimeter of 25 m side a is 2 m shorter than twice side b and side c is 3 m longer than side b what are the three sides?

a = 2b - 2
c = b + 3
so 2b - 2 + b + b + 3 = 25
that is, 4b + 1 = 25 ie 4b = 24 and so b = 6
then a = 2b - 2 = 12 - 2 = 10
and c = b + 3 = 6 + 3 = 9
So the three sides are 10m, 6m and 9m.

The shorter side of a rectangle has a length of x inches the longer side has a lenght of 2x-1 in If the perimeter is 58 in find the length of the sides?
shorter side = 10 longer side = 19
Which side of a rectangle is the length?
Either of the longer and shorter sides, but the length is usually the longer side and width is usually the shorter side.
Are diagonals always longer than the sides?
On squares and rectangles, yes. But on parallelograms and rhombus the one diagonal can be shorter than one of the sides.
What are the properties of a kite?
The intersection of the diagonals of a kite form 90 degree (right) angles. This means that they are perpendicular. The longer diagonal of a kite bisects the shorter one. This means that the longer diagonal cuts the shorter one in half. It is a 4 sided quadrilateral Its 4 interior angles add up to 360 degrees It has no parallel sides Its adjacent sides are equal It has 1 pair of opposite angles that are equal It has 2 diagonals that intersect each other at right angles Its perimeter is the sum of its 4 sides Its area formula is: 0.5 times product of its diagonals

How do you find the sides of an octagon with perimeter?
You say these things to yourself: -- "The perimeter is the distance all the way around the octagon." -- "The octagon has eight sides." -- "So, if it's a 'regular' octagon, then all the sides are the same length, and each side must be 1/8 of the perimeter." -- If it's not a 'regular' octagon, then it has some longer sides and some shorter ones, and the perimeter doesn't help me find the lengths of the sides.
Are the diaganols of a square longer or shorter than its sides?
longer
What is the perimeter of a triangular room if all the sides are 4.5 meters long?
i think 9 meters
Does a rectangle have to have 2 longer sides and 2 shorter sides?
If it did not, it would be a square.
How do you find the perimeter in a parrallelogram?
Add together the lengths of the 4 sides, or you could add the length of one shorter side to one longer side and then double it. e.g. Perimeter of parallelogram = l = b = l = b, or 2(l + b)
Does a trepezuim have curved sides?
No a trapezium is a rectangle wit one of the longer sides shorter
Which side of a rectangle is the length?
Either of the longer and shorter sides, but the length is usually the longer side and width is usually the shorter side.
The perimeter of a rectangle is 54 meters.The longer side is three more than the shorter side.Find the length of each side.Please explain?
This is technically algebra. SO LETS DO THIS!!!! We have to make an unknown and find it. Lets make x into this unknown and the shorter side into x. If the longer side is 3 more than the shorter side, that means that the longer side is equal to x+3 because you have the shorter side and you have to add 3 more to it to get the longer side. Now that you know what all sides are( x, x, x+3, and x+3) we can now solve. Since the perimeter of a rectangle is 54 meters and perimeter is the length of the sides put together, we simply have to add all the sides together. If we do this, we get x+x+x+3+x+3=54. To put it shorter, combind the x's and the 3's. Now it becomes 4x+6=54. Minus 6 from both sides, and you get 4x=48. Divide 4 from both sides, and you see that x=12. I hope I explained the question enough, and have a nice day.
A right triangle has one leg three times as long as the other Find a function that models its perimeter P in terms of the length x of the shorter leg?
The perimeter is the sum of all of the sides of the triangle. If the shorter leg is x, the longer leg is 3x. The hypotenuse is then the square root of x^2 + 3x^2, or 2x. Then the perimeter is x + 3x + 2x, simplified, f(x) = 6x.
A heptagon has perimeter 121 feet . Four of the sides are the same length, and the remaining sides are half as long. How long are the shorter sides?
The answer will be 30.25
