To find AB(x) and BC(y), you can do(there are multiple ways you can do this):
tan A = 
tan 60° = or (tan 60°) · 7 = y
tan 60° = 
√3 · 7 = y
7√3 cm = y
sin B = 
sin 30° = or 
sin 30° = 
= 
x = 
x = 14 cm
AB = 14cm
BC = 7√3 cm
Times the ones in () which becomes 120 * 224 = 0.535
Using the formula for area for a parallelogram, A=BH, where A is area, B is Base, and H is height, you follow that. So in this case, you would want to find one of the area's then multiply it by 4. So for the area you get 20.52 meters. If you multiply it by 4, you get 82.08 meters. Have a nice day!
