### A sail has a a spread of canvas as shown in the figurefind the surface area of one side of the sail?

### A sail boat has a mast that holds a triangular sail. The sail has a base of twelve meters and a height of nine meters. The cost of the sail is 15 per square meter.What will it cost to make the sail?

Because your right triangle is half of a rectangle, you would multiply one measurement by the other and then divide that by two. Then multiply that by 15 per square meter. Unfortunately, this will UNDER estimate your cost, as the triangular sail's hypotenuse is NOT a straight line. But it'll get you 'in the ballpark'.

### The length of the largest sail along the mast is 82.5 feet The length of the diagonal portion of the sail is 90.3 feet What is the length of the sail along the boom Answers are rounded to the near?

I will assume the sail is shaped like a triangle- actually a right triangle. like: |\ 82.5 | \ 90.3 ........|__\ ..........B where B is the length along the boom. If this is true, then you can use a2 + b2 = c2 to solve the problem 82.52 + B2 = 90.32 B2 = 90.32 - 82.52 B = square root of (90.32 - 82.52) B = square root of (8154.09 - 6806.25) B =…

### Is there a diagram on how to make a paper boat?

WikiAnswers is not an image site, so no, we don't have diagrams. Here's how to make a paper boat, though: Take a square piece of paper - you can check to be sure it's square by folding it diagonally - a square will fold evenly into a triangle with no paper hanging out left over (you can cut off the extra to make it square if you want) Fold the paper in half and crease…

### Why was the triangular lateen sail an improvment over the old square-rigged sail?

The lateen sail was used at the same time a square sail was used, but has different uses. The square sail is fine if you have a heavy boat and always fiind a wind that is blowing in the direction you want to go. Under such conditions, a lateen sail isn't much of an improvement. It was only once boats were made lighter (to faster get from the Atlantic to the Orient) that the triangular…

### What is the trade pattern of slavery between Europe Africa and the Americas?

The beginning of the socalled triangle trade route began sometime after Columbus had reached the Western Hemisphere. Generally speaking, this triangle of trade was in full force by the end of the 16th century. The triangle would develop over the centuries. It's beginning was when ships from western Europe would sail to the western coast of Africa, obtain slaves via capture, deals with tribal chiefs or Islamic slave traders. The ships then began the second…

### Why are sails a triangle?

Two thousand years ago, triangular sails appeared. With proper orientation, these sails could convert wind power from any direction into forward thrust. The sail might be pushed or pulled by the wind force, and the pull was stronger than the push. Although there was no physical understanding of the pulling force, it allowed the boat to sail into the wind.
