You can put this solution on YOUR website! Draw this. Make an altitude x.
The sin 30=x/7
x=3.5
area is length*altitude=10*3.5=35 sq units
The area of a parallelogram is the product of its two adjacent sides measures and the sine of the concluded angle
area of the parallelogram = sin(30°)*7*10 = = 7*5 = 35 square units. ANSWER
