To calculate the area of a trapezoid, you have to know the lengths of three sides because 1/2*(sum of parallel sides)*perpendicular height = area

How do you calculate the perimeter of a trapezoid with three sides?
You cannot have a trapezoid with three sides! Or if the question was something like 'You know three of the four sides of a trapezoid' ; that cannot be done either, because there is no way of calculating what the length of the fourth side is.
What is the area of a trapezoid that has a perimeter of 230?
Not enough information. To calculate this you must know the altitude or height.
How do you find the height of a trapezoid if you already know the area?
1/2*(sum of parallel sides)*height = area height = (2*area) divided by (sum of parallel sides)
If you know the perimeter of a rectangle but not the length of its sides can you calculate its area?
yes
How do you calculate area of shape has 5 sides?
You need to know the lengths of a few sides, but check out the link for clear calculations.

Difference with trapezoid and isosceles trapezoid?
If the two sides which are not parallel have equal lengths, then the trapezoid is called an isosceles trapezoid (standard trapezoid has unequal sides). The base angles in an isosceles trapezoid are equal in measurement, also I know that a trapezoid with two nonparallel sides the same length is called an isosceles trapezoid.
If you know the perimeter of a rectangle but not the length of its sides can you calculate its area?
yes
Can you calculate the area if you know the perimeter?
No, you can not calculate an area if you know just the perimeter. For example, rectangle with sides of 10 and 20 would have a perimeter of 60 and an area of 200, but a square of sides 15 would have a perimeter of 60 and an area of 225. You need to know more details about the shape than just the perimeter.

What is the area of a trapezoid if the perimeter is 32?
Unlike a square, knowing the perimeter of a trapezoid is not enough to be able to calculate its area. Think of a rectangle with a perimeter of 20cm. One possibility is that it has a length of 8cm and a width of 2cm. This would give and area of 16cm2. However the rectangle could have also had a length of 7cm and a width of 3cm as this would also give a perimeter of 20cm. However this rectangle now has an area of 21cm2. To be able to calculate the area of the trapezoid, you would need to know more about it than just its perimeter.
How do you find the perimeter of an isosceles trapezoid if you don't know two sides?
you dont
What are the attributes that make a parallelogram a special trapezoid?
First, there is no such word as trapozoid: it is trapezoid although most of the world know it as a trapezium.Whereas a trapezium has one pair of parallel sides, a parallelogram has two pairs of parallel sides.

What is the area of a trapezoid if the meausure of the base is 8 and the height is 5?
Area of a trapezoid = 0.5*(sum of parallel bases)*height Need to know the measure of the other base
