It is: perimeter minus hypotenus+base = height Area = 0.5*base*height


How you solve parallelogram?

Please clarify what data is given, and what you want to solve for. To calculate the perimeter, add the length of all four sides. To calculate the area, the formula is basically same as for a rectangle: length x height; however, the height must be measured perpendicular to the side which you use as "length".


What is the formula for finding the perimeter of a triangle when given the base and the height?

You multiply the base and the height and then you divide the answers of that by 2. :)

all you have to do is add together the four sides. 2L+2W=Perimeter (L=length or base, W=Width or height)

In that case, it would be good to know WHAT is given. If NOTHING is given, you really can't calculate.


How do you calculate the sides of a parallelogram given the height and longer diagonal?

The height and longer diagonal do not provide enough information to calculate the sides.


The sum of the perimeters of two congruent triangles is three times the perimeter of the first triangle?

Let's denote the perimeter of the first triangle as P. Since the triangles are congruent, the perimeter of the second triangle is also P. The sum of their perimeters is then 2P. According to the given statement, this sum is three times the perimeter of the first triangle. So we have the equation 2P = 3P. Simplifying, we find that P = 0, which is not a valid solution. Therefore, there is no triangle for which the sum of the perimeters of two congruent triangles is three times the perimeter of the first triangle.


What is the length in inches of a triangles altitude if its base is thirty-two inches?

I suppose by "length of a triangles altitude" you mean height. The height of the triangle in question cannot be determined from the information given. In order to determine the height of the triangle, two dimensions must be known.
