What is the area of a trapezoid that has a perimeter of 230?

Not enough information. To calculate this you must know the altitude or height.


What is the lengthof the altitude if the bases of trapezoid are 30m and 20m and the area is 108 squared m?

4.32m Check: 0.5*(30+20)*4.32 = 108 square m


How do you find the area of a rhombus parallelogram and trapezoid?

Rhombus :1. The "base times height" method First pick one side to be the base. Any one will do, they are all the same length. Then determine the altitude - the perpendicular distance from the chosen base to the opposite side. The area is the product of these two, or, as a formula: whereb is the length of the basea is the altitude (height).2. The "diagonals" method Another simple formula for the area of a rhombus when you know the lengths of the diagonals. The area is half the product of the diagonals. As a formula: whered1 is the length of a diagonald2 is the length of the other diagonal2. Using trigonometry If you are familiar with trigonometry, there is a handy formula when you know the length of a side and any angle: wheres is the length of any sidea is any interior anglesin is the sine function (see Trigonometry Overview) It may seem odd at first that you can use any angle since they are not all equal. But the angles are either equal or supplementary, and supplementary angles have the same sine.Parallelogram:The area of a rectangle is given by the formulawhereB is the length of any baseA is the corresponding altitude Recall that any side can be chosen as the base. You must use the altitude that goes with the base you choose. The altitude (or height) of a parallelogram is the perpendicular distance from the base to the opposite side (which may have to be extended).Trapezoid:Area formula The area of a trapezoid is given by the formulawhereb1, b2 are the lengths of the two basesa is the altitude of the trapezoidCalculator Recall that the bases are the two parallel sides of the trapezoid. The altitude (or height) of a trapezoid is the perpendicular distance between the two bases. This is equivalent to the altitude times the average length of the bases. Since the median of a trapezoid is also the average length of the two bases, the area is also the altitude times the median length. Area as a compound shape Another way to find the area of a trapezoid is to treat it as some simpler shapes, and then add or subtract their areas to find the result. For example, a trapezoid could be considered to be a smaller rectangle plus two right triangles:


How do you find height of a trapezoid?

What is a trapezoid with congruent diagonals?

The area formula for a trapezoid?

The area of a trapezoid is one-half the product of the length of an altitude and the sum of the lengths of the bases: A=1/2(b1 + b2)

What is the area of a trapezoid?

The area of a trapezoid = 1/2 (altitude)(base 1 + base 2) *altitude can also be called the height, or the spacing between the parallel sides. Base 1 is the length of one of the parallel sides, and base 2 is the length of the other parallel side.


What is the definition for the word altitude in math?

Altitude is the math term that most people call height. The altitude is always perpendicular to base. The altitude of a triangle is the distance from one side (or an extension of that side) to the opposite vertex. The altitude of a parallelogram or trapezoid is the distance from one side (or an extension of that side) to the opposite side. Since the altitude must be perpendicular to the base, it is the term used for figures which do not have a right angle. Right triangles, squares, and rectangles, which have a right angle, do not require an altitude because the height is one of the sides of the figure.


What is the lengthof the altitude if the bases of trapezoid are 30m and 20m and the area is 108 squared m?

4.32m Check: 0.5*(30+20)*4.32 = 108 square m


Is a trapezoid always an isosceles trapezoid?

No, not every trapezoid is an isosceles trapezoid.
