Trapezoid
A trapezoid is a quadrilateral with only one pair of parallel sides
A trapezoid is a quadrilateral with only one pair of parallel sides. The parallel sides are called the bases of the trapezoid, and the non-parallel sides are called the legs. The legs can be of different lengths, while the bases are always parallel and of equal length.
To find the area of a trapezoid, you can use the formula:
Area = (1/2) * (sum of bases) * (height)
Here’s an example to help illustrate this:
Suppose we have a trapezoid with bases measuring 8 units and 12 units, and a height of 5 units. To find the area, we can use the formula:
Area = (1/2) * (8 + 12) * 5
= (1/2) * 20 * 5
= 10 * 5
= 50 square units
So, the area of this trapezoid is 50 square units.
It’s important to note that the height of the trapezoid is always perpendicular to both bases. If the trapezoid is not drawn to scale or has some irregularities, finding the height might require some additional calculations. In some cases, you may need to apply the Pythagorean theorem or use similar triangles to determine the height.
Additionally, if you are given the lengths of the legs instead of the bases, you can still find the area using the formula by following these steps:
1. Find the length of one of the bases by subtracting the length of the shorter leg from the length of the longer leg.
2. Use the lengths of the legs as your bases and follow the earlier steps to find the area.
