In a trapezium (trapezoid), the upper base (b1) and lower base (b2) can be found using the formula for the area (A) if the height (h) is known:
[ A = \frac{1}{2} \times (b1 + b2) \times h ]
Rearranging this formula allows you to solve for one base if you have the area, the other base, and the height. For example, if you know the area and one base, you can isolate the other base:
[ b1 + b2 = \frac{2A}{h} ]
Thus, you can find either base by substituting the known values.

What is the formula for finding the area of a trapazoid?
Area = (1/2) x (height) x (length of lower base + length of upper base)
What are the lower and upper base angles in a trapezoid?
In a trapezoid, the lower base angles are the angles formed between the base and the legs of the trapezoid on the bottom side, while the upper base angles are those on the top side. For an isosceles trapezoid, the lower base angles are congruent to each other, as are the upper base angles. The sum of the lower and upper base angles equals 360 degrees, with each pair of adjacent angles summing to 180 degrees.
How is the formula for the area of a trapezoid related to the formula for the area for a triangle?
The formula for the area of a trapezoid is A = 1/2 (b1 + b2)/h where b1 is the upper base of the trapezoid , b2 is the lower base of the trapezoid and h is the height of the trapezoid. Since a triangle has only one base , replace either b1 or b2 with zero. Thus the area of a triangle is A = 1/2bh
How is the formula of a trapezoid related to the formula of a parallelogram?
Suppose you have a trapezium whose parallel sides (bases) are of lengths A and B units, and where the height is h units If you flip a trapezium over and append it to the original along one of the bases you will have a parallelogram whose base is A+B units in length and whose height is h units. So 2*Area of trapezium = Area of parallelogram = (A + B)*h
What is the correct formula to calculate area of a trapezium?
A = 1/2 (b1 + b2) h b1 = base 1 (usually the bottom) b2 = base 2 (usually the top) h = height
Can you show me a worken out formula of a trapezium?
formula= base times height
What is the formula for finding the area of a trapazoid?
Area = (1/2) x (height) x (length of lower base + length of upper base)
What do you do for the musical ornament of a mordent?
There are two types of mordents: upper and lower. For the upper modent, you play a rapid succession of the base note, upper note, then base note. For the lower, you do the same but it will be the base note, lower note, then base note.
What are the lower and upper base angles in a trapezoid?
In a trapezoid, the lower base angles are the angles formed between the base and the legs of the trapezoid on the bottom side, while the upper base angles are those on the top side. For an isosceles trapezoid, the lower base angles are congruent to each other, as are the upper base angles. The sum of the lower and upper base angles equals 360 degrees, with each pair of adjacent angles summing to 180 degrees.
Can a quadrilateral have each of 4 angles a different measure?
Yes, be it a common convex quadrilateral or a concave quadrilateral. For a convex quadrilateral, the most obvious example is a irregular trapezium, where the upper base and the lower base are of different length, and the slanted sides are of different length. It is similar for a concave quadrilateral.
How do you work out the area of a trapizuim?
First you write the formula for the area of a trapezium, either from memory or by looking it up. Then you substitute the lengths of the sides in your trapezium for each of the appropriate terms in the formula. Oh, all right: Area = 1/2 (height) x (length of base-1 plus length of base-2).
How are the upper region and lower region different?
The upper region base rolling hills and rich river valleys and the lower sandy beaches
Formula for volume of 3D trapezium?
volume of trapezium = 1/2* (a1+a2)*h* length where a1,a2 are the base areas respectively and h is the height its a good formula but here is a easier one 1/2*(Area of top + Area of bottom)*Height*lenght
How is the formula for the area of a trapezoid related to the formula for the area for a triangle?
The formula for the area of a trapezoid is A = 1/2 (b1 + b2)/h where b1 is the upper base of the trapezoid , b2 is the lower base of the trapezoid and h is the height of the trapezoid. Since a triangle has only one base , replace either b1 or b2 with zero. Thus the area of a triangle is A = 1/2bh
How is the formula of a trapezoid related to the formula of a parallelogram?
Suppose you have a trapezium whose parallel sides (bases) are of lengths A and B units, and where the height is h units If you flip a trapezium over and append it to the original along one of the bases you will have a parallelogram whose base is A+B units in length and whose height is h units. So 2*Area of trapezium = Area of parallelogram = (A + B)*h
How many acute angles does a trapezoid have?
A trapezoid always has two acute angles. the base angles have to be acute because the lower base angles and the upper base angles are complementary so since the upper base angle is always obtuse, the lower base angles have to be acute.
What is the formula to work out the area for a trapezium?
Area = a [(b1 + b2)/2]a = altitude (height) of the trapezoidb1 = length of one baseb2 = length of the other base
