Parallelogram

We know about parallelogram ABCD: length |AB| = 76cm, |BC| = 44cm, and angle ∢BAD = 30°.

Find the area of the parallelogram.

Correct answer:

S =  1672 cm2

Step-by-step explanation:

a=76 cm b=44 cm BAD=30° rad=30° 180π =30° 1803.1415926 =0.5236=π/6 h=b sin(BAD)=44 sin0.5236=22 cm S=a h=76 22=1672 cm2
