To find the area of a parallelogram, you use the area formula:
Area = Base * Height
Then, all you have to do is substitute in your known integers and solve. Therefore:
Area = 15 * 21 2/3
When we multiply these two numbers, we get
Area = 325 square yards or yards
Answer:
9/10
Step-by-step explanation:
Dividing by a fraction is the same as multiplying by that fraction's reciprocal (basically the fraction flipped).
÷
= 
I think you're having trouble because the equation you wrote for 8a has a slight typo.
The question says that the length is 9 less than twice the width. Your equation states the length is 9 times the width minus 2. So the length actually equals 2w – 9, meaning that w(2w – 9) = 180
Hope this helps! If you're still having trouble, let me know :)
