Question

Find the area of parallelogram ABCD given AB=12cm, AD=20 cm, and angle A=30 degrees.

Answer 1

is it 120

Answer 2

how did it come out to 120

Answer 3

is it correct

Answer 4

in finding the area, the altitude is required,.

to find the the altitude, the formula will be,.

sin 30 deg = h/12
therefor, height or altitude = 12sin 30 deg

therefor the solution will be.

Area = base (height)
= 20 (12sin 30) = compute. . .
