Find the area of a trapezoid?
Area measured in square units = 1/2*(sum of parallel sides)*height If a and b are parallel, and b>a ((a+b) sqrt((a-b+c-d) (a-b-c+d) (a-b+c+d) (-a+b+c+d)))/(4 (b-a))
A circular table with a diameter of 6 feet has an area of square feet?

What is the area of a circle with the circumference 6.28?
To find the area of a circle when given the circumference, you can use the formula A = (C^2) / (4π), where A is the area, C is the circumference, and π is approximately 3.14159. In this case, with a circumference of 6.28, the area would be (6.28^2) / (4 * 3.14159) ≈ 5 square units.
Diagonal of a square whose area is 36?
The diagonal of a square whose area is 36 is the square root of 72, or about 8.49. Since the area of a square is side(squared), then the sides are each 6. Then since a(squared) + b(squared) = c(squared), for a triangle (the diagonal), you get the square root of 72.
Assume the following measurements. X 8 feet. Y 20 feet. The region 'a' has an area of 40 square feet. The region 'b' has an area of 65 square feet. What is the area of region 'c'?
XY = area of the rectangle. We know the region 'a' and 'b', but are left with two unknowns: region 'c' and the gray area. Since we have no data on the gray area, we can't know region 'c
