1.	Find the area of a parallelogram ABCD, AB = 6.5 cm and DE = 4 cm,where DE is perpendicular to AB
Answer» Answer: ABCD is a parallelogram with AB = 4cm and BC = 6 cm and 30 deg. What is the area of the parallelogram? DRAW CE as a perpendicular from C onto AB. CE = BC sin 30 = 61/2 = 3 cm. HENCE area of the parallelogram = ABCE = 4*3 = 12 sq cm.

Answer:

ABCD is a parallelogram with AB = 4cm and BC = 6 cm and 30 deg. What is the area of the parallelogram?

DRAW CE as a perpendicular from C onto AB. CE = BC sin 30 = 6*1/2 = 3 cm. HENCE area of the parallelogram = AB*CE = 4*3 = 12 sq cm.
