Area = 1/2*(sum of the two bases)*height


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 an area of a trapezoid with bases of 12cm and 3cm and height is 9cm?

The formula for finding the area of a trapezoid is:A = (1/2) (b1 + b2 ) h


How do you find the height of a trapezoid given the area and bases?

Oh, dude, finding the height of a trapezoid given the area and bases is like finding your way out of a corn maze blindfolded. You just use the formula for the area of a trapezoid, which is (base1 + base2) * height / 2, and then rearrange it to solve for height. It's simple math, but hey, who needs to know the height of a trapezoid in real life anyway, right?


Why is the formula for area of a triangle and area of a trapezoid are what they are?

area triangle = 1/2 base times height area trapezoid = 1/2 (sum of bases) times height


How do you calculate the area of a trapezoid?

To calculate the area of a trapezoid, you can use the formula: Area = 0.5 * (sum of bases) * height. Simply add the lengths of the two parallel sides (bases) of the trapezoid, multiply the sum by the height, and then divide by 2 to find the area.


Formula to find the median of a trapezoid?

To find the median of a trapezoid, you would add the lengths of the two bases of the trapezoid and then divide by 2. This will give you the median, which is the segment connecting the midpoints of the two non-parallel sides of the trapezoid.


Can a trapezoid have 3 bases?

No, a trapezoid cannot have 3 bases. A trapezoid is a quadrilateral with exactly one pair of parallel sides. The parallel sides are called bases of the trapezoid. Therefore, there can only be 2 bases.


What is height of trapezoid with area of 9 and bases of 2.4 and 3.6?

To find the height of a trapezoid with the given area and bases, you can use the formula for the area of a trapezoid: A = (1/2)(b1 + b2)(h), where A is the area, b1 and b2 are the bases, and h is the height. Rearranging the formula, we can calculate the height as: h = 2A / (b1 + b2). Therefore, the height of the given trapezoid is: h = 2(9) / (2.4 + 3.6) = 2.25 units.


The median of a trapezoid bisects the bases of the trapezoid?

The altitude of a trapezoid bisects the bases of the trapezoid.


A trapezoid has bases of 7 centimeters and 5 centimeters and a height of 3 centimeters What is its area?

The formula for area a is height X average of the two parallel bases of the trapezoid. In this instance, a = 3[(7 + 5)/2] = 18 square centimeters.


What is the formula to find the bases of an isosceles trapazoid?

There is no simple formula and, in any case, the answer will depend on what information about the trapezoid is given.
