How do you find the missing side of a triangle with a perimeter of 40?
It depends on what is known about the triangle.
How do find the perimeter of a triangle?
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.
How do you find the perimeter of a rectangle if you have the length and the area?
Area = Length*Width so Width = Area/Length. Therefore the Width can be calculated. Then, perimeter = 2*(Length + Width) and everything on the right hand side of the equation is known so the perimeter can be calculated.
How do you find perimeter of a triangle if length of one side is not known?
Pythagorean Theorem- a2+b2=c2 Then add up all of the sides and you get the perimeter. LOOPDOP says: Previous answer will only be correct for a right angled triangle where c= the hypotenuse. For other triangles it is a bit more complicated. You will need to now the angle between the two known lengths. a and b are the two known lengths C is the angle between a and b length of third side = the square root of {a2 + b2 - (2ab x cos C)}
What is the area of a rectangle that its perimeter is 39?
156 It is impossible to calculate the area of a rectangle from its perimeter if no other dimension is known. The area of a rectangle is the product of its length and width, and the perimeter is twice the sum of its length and width.
How do you find the perimeter of a triangle when only the base and area are given?
A = 1/2bh then you use Pythagoras theorem to find the length of the other 2 sides, using the known value for the height and 1/2 of the bases value.
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.
If the perimeter of a rectangle is 14 inches then its area is 10 inches?
the length is 5 and the height is 2 or also known as 5x2

How much is perimeter?
The perimeter is the measure of length of the boundary of a 2-dimensional object. The most common mathematical objects in this category are squares, rectangles, circles and triangles. The perimeter of a square = 4d (where d is the length of 1 side) The perimeter of a rectangle = 2l + 2w (where l is the length and w is the width) The perimeter of a circle = 2πr (where π is the mathematical constant pi and r is the radius. The perimeter of a circle is better known as the circumference) The perimeter of a triangle is the total length of all three sides.

How do you find the perimeter of an isosceles triangle when you only have one side and the base?
If you mean "isosceles" triangle, the perimeter is the sum of twice the known side plus the base.
How do you find the area of a triangle while knowing the length of three sides?
Area of Triangle when the length of the three sides is known: square-root [P * (P-2a) * (P-2b) * (P-2c)] / 4 where P is total perimeter and a, b and c are the lengths of the three sides.
Can you find the perimeter if you know area of a rectangle?
You can find the perimeter of a rectangle if you know its area and the length of one side. Divide the area by the length of the known side and the quotient will be the length of a side perpendicular to the known side, and then multiply the sum of the two sides by two to find the perimeter.
How do you find the perimeter of a rectangle if you have the length and the area?
Area = Length*Width so Width = Area/Length. Therefore the Width can be calculated. Then, perimeter = 2*(Length + Width) and everything on the right hand side of the equation is known so the perimeter can be calculated.
