What is the missing length so we have the front base is 12 mm and then the area equals 42 mm with a small two on top so we need to know what the letter S equals in millimeters

1 answer

The formula for the area of a trapezoid is 1/2 * (sum of bases) * height.

Given that the front base is 12 mm, the area is 42 mm^2, and the height is unknown, we can set up the equation:

42 = 1/2 * (12 + S) * h

To find the value of S (the missing length), we need more information about the trapezoid, such as the height. Without that information, we cannot determine the value of S.
