Check: 0.5*(30+20)*4.32 = 108 square m
To find the altitude of a trapezoid, you can use the formula for the area of a trapezoid, which is ( A = \frac{1}{2} (b_1 + b_2) h ), where ( b_1 ) and ( b_2 ) are the lengths of the two parallel sides and ( h ) is the altitude. Rearranging this formula allows you to solve for the altitude: ( h = \frac{2A}{(b_1 + b_2)} ). If the area is not known, you can also use geometric methods, such as constructing perpendicular lines from the non-parallel sides to the bases to measure the height directly.
The bases on a trapezoid are the two lines that are parallel to each other. .............................. ....____base____...... .../ ...................\..... ../ .....................\.... ./_____base_____\... .............................
If a segment is parallel to the bases of a trapezoid, it is indeed the median of the trapezoid. The median connects the midpoints of the non-parallel sides and is equidistant from both bases. Additionally, the length of the median is the average of the lengths of the two bases. Thus, it effectively bisects the trapezoid into two smaller trapezoids.
The area ( A ) of a trapezoid can be calculated using the formula: [ A = \frac{1}{2} \times (b_1 + b_2) \times h ] where ( b_1 ) and ( b_2 ) are the lengths of the two bases, and ( h ) is the height (altitude). Substituting the given values, ( b_1 = 3 ) in, ( b_2 = 11 ) in, and ( h = 8 ) in: [ A = \frac{1}{2} \times (3 + 11) \times 8 = \frac{1}{2} \times 14 \times 8 = 56 \text{ square inches.} ] Thus, the area of the trapezoid is 56 square inches.
The bases of a trapezoid are either of its parallel sides.
The altitude of a trapezoid bisects the bases of the 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)

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.
A trapezoid does not have three bases!
False.
If a segment is parallel to the bases of a trapezoid, it is indeed the median of the trapezoid. The median connects the midpoints of the non-parallel sides and is equidistant from both bases.
