The area of a kite:
To find the area of a kite, multiply the lengths of the two diagonals and divide by 2 (same as multiplying by 1/2):

Area of kite = (1/2)ab

The area of a parallelogram:

parallelogram To find the area of a parallelogram, just multiply the base length (b) times the height (h):

Area = b x h
