Too tired to use google?STS said:diagonal 1=20cm.

Okay, that makes sense.STS said:diagonal 1=20cm.
diagonal 2=37cm.
AB=25.5cm
What?? What is "S( )"? What is "M"? Is it another point? The midpoint where the two diagonals intercept?S (AMC)= 306cm.
S (ABCD)=?

OK; then WHY did you post only this:STS said:S is the area. You move one of the diaganals to the side, then that forms a triangle. Then with Heron's formula you figure out the area of the triangle that has formed (AMC). That is suppose to help you figure out the area of the parallelogram using another formula, but I couldn't figure it out.
A parallelogram is a four-sided shape with opposite sides that are parallel and equal in length. It also has opposite angles that are equal in measure.
To find the area of a parallelogram, you can use the formula A = base x height, where the base is the length of one of the parallel sides and the height is the distance between the two parallel sides.
The diagonals of a parallelogram are the line segments that connect opposite corners of the shape. They bisect each other and divide the parallelogram into two congruent triangles.
To find the length of the diagonals in a parallelogram, you can use the Pythagorean theorem. The length of the diagonal can be calculated by taking the square root of the sum of the squares of the lengths of the two adjacent sides.
Yes, you can use the formula A = 1/2 x d1 x d2, where d1 and d2 are the lengths of the diagonals, to find the area of a parallelogram if you only know the length of the diagonals.
