The area of trapezoid is A= 1/2 h(b1+b2) where A = area, h = height, and b1 and b2 = bases.
To find the area of a trapezoid, you can use the formula A = 1/2 h(b1 + b2), where A represents the area of the trapezoid, h represents the height of the trapezoid, and b1 and b2 represent the lengths of the two parallel bases of the trapezoid.
To use this formula, follow these steps:
1. Identify the height and bases of the trapezoid. The height is the perpendicular distance between the two bases of the trapezoid, and the bases are the two parallel sides of the trapezoid.
2. Measure or calculate the height and the lengths of the two bases.
3. Plug the height and the lengths of the bases into the formula A = 1/2 h(b1 + b2).
4. Multiply the height by the sum of the lengths of the two bases, then divide the result by 2. This will give you the area of the trapezoid.
For example, if you have a trapezoid with a height of 5 units, a base of length 3 units, and another base of length 7 units, you can calculate the area as follows:
A = 1/2 * 5 * (3 + 7)
A = 1/2 * 5 * 10
A = 2.5 * 10
A = 25
Therefore, the area of the trapezoid is 25 square units.
