But what if you don't know the height h? We can prove the area of a trapezoid formula by using a triangle here. Step 4: Identify b1 and b2 (lengths of the bases) of the trapezoid and h (height) of the trapezoid. The median (also called a midline or midsegment) is a line segment half-way between the two bases. These are all different This image is not<\/b> licensed under the Creative Commons license applied to text content and some other images posted to the wikiHow website. The formula for the area of a trapezoid is A = (b1+b2)h, where b1 and b2 are the lengths of the bases and h is the height. Find the lengths of the legs of the trapezoid, using the formula for the sine of an angle: Subtract the values of a, c, and d from the trapezoid perimeter to find the length of the second base: b = P - a - c - d = 25 - 4 - 12 - 7.325 = 1.675 cm. The formula for the area of a trapezoid is A = (b 1 +b 2 )h, where b 1 and b 2 are the lengths of the bases and h is the height. A right trapezoid (also called a right-angled trapezoid) has two adjoining right angles. Then, if the trapezoid's height was 10 inches, you'd add that to 20 and get 30. The surface area #S = 2*A_(Base) + "Lateral Surface Area"#. Therefore, the total area of the prism is 1840 cm.
