Area of a trapezoid
1/2h(b1+b2) where h is the perpendicular height, b1 is base one, b2 is base 2
The area of a trapezoid can be calculated by using the formula:
Area = (b1 + b2) * h / 2
where b1 and b2 represent the lengths of the parallel sides of the trapezoid and h represents the height of the trapezoid.
To use this formula, you need to know the values of b1, b2 and h. You can measure these values if you have a physical trapezoid, or you can be given these values in a problem.
Once you have the values of b1, b2 and h, you can plug them into the formula and simplify it to get the area of the trapezoid.
For example, let’s say you have a trapezoid with b1 = 5 cm, b2 = 8 cm and h = 3 cm. Using the formula:
Area = (b1 + b2) * h / 2
Area = (5 + 8) * 3 / 2
Area = 39 / 2
Area = 19.5 square cm
Therefore, the area of the trapezoid is 19.5 square cm.
