The perimeter of an object is simply the length of its border, so the perimeter of a triangle is the sum of the lengths of its 3 sides.The area of a triangle is equal to half of its base times its height, for example if a triangle had a base of length 4 and was 5 units tall, it would have an area of (4*5)/2, or 10 units2.
The easiest way is if you already have the lengths of all three sides of the triangle. In which case, you simply add their lengths together to acquire the perimeter. However, if you only have the lengths of two sides of a triangle, and it's a right triangle"; you can use the Pythagorean Theorem to determine the length of the third side. Note: Here are some quick definitions of terms that will be used in the following equations. A² will represent the height of the triangle. B² will represent the width of the triangle. C² will represent the hypotenuse of the triangle. The "Hypotenuse" is the longest side of a triangle. A "Right Triangle" is a triangle that has an angle measuring 90°. When using the Pythagorean Theorem; if you're attempting to find hypotenuse of a triangle; you use the formula "A² + B² = C²". That is; you square the two known sides; then add the products. Upon doing that, find the square root of the sum of both numbers, and you have the length of the hypotenuse. Upon finding the missing side's length; add the lengths of all three sides, and the resulting number will be the perimeter of the triangle. If you have the length of one side, and the hypotenuse of a right triangle; and are seeking to find the third side's length; you use the formula "C² - A² = B²" or "C² - B² = A²"; depending on which side your attempting to find the length of. Like in the previous equation, add the lengths of all three sides together to acquire the perimeter.
Yes. Scalene simply means that a triangle's sides are all different lengths. Obtuse means that a triangle has an obtuse angle. Therefore, you can have an obtuse scalene triangle.
To answer this question, use the pythagorean theorem: a^2+b^2=c^2, where a and b are leg lengths and c is the length of the hypotenuse. Then isolate c, the length of the hypotenuse. c=sqrt(a^2+b^2) At this point, simply plug in the leg lengths, 5 and 7, in for a and b. c=sqrt(5^2+7^2) c=sqrt(25+49) c=sqrt(74)
That really depends what else you know about the triangle. For example, if you only know the lengths of two sides, you simply don't have enough information.
Simply measure them.
The lengths of a scalene triangle are of 3 different sizes and it also has 3 different interior angles that add up to 180 degrees.
A scalene triangle is simply a triangle where all of its sides are different lengths. One example of the side lengths of a scalene triangle are: 5cm, 6cm and 7cm
Simply measure it.

Yes. Scalene simply means that a triangle's sides are all different lengths. Obtuse means that a triangle has an obtuse angle. Therefore, you can have an obtuse scalene triangle.
The perimeter of a triangle is simply the sum of the lengths of its three sides. Knowing that it is right angles (or not) is rarely of help.
If the triangle is equilateral, you simply divide the perimeter by three to find the length of each side. If the triangle is not equilateral, you will need more information to determine the length of each side.

Sometimes. "Scalene" simply means that the three sides have different lengths. This does not imply that the triangle has to have an obtuse angle.
