A parallelogram has sides A, B, C, and D. Sides A and B have a length of #2 # and sides C and D have a length of # 7 #. If the angle between sides A and C is #pi/4 #, what is the area of the parallelogram?

Answer 1

The area of the parallelogram is equal to the cross product of the vectors representing, #vec(A) and vec(C)#,
#A_diamond=vec(A)xxvec(C)= |A||C| sin(pi/4)#
#A_diamond= |A||C| sin45^o = 2*7*sqrt(2)/2=7sqrt(2)#

Given a parallelogram has side with #A=B=2# and C=D=7
Angle between #A and C, alpha=pi/4#
Required Area, #A_(diamond)# of parallelogram?
Definition and Principles:
#Area_diamond= |A||C| sin(pi/4) =|A||C| sin45^o = 2*7*sqrt(2)/2=7sqrt(2)#

To find the area of the parallelogram, we can use the formula: Area = base × height. The base of the parallelogram is the length of one of its sides, and the height is the perpendicular distance between the base and the opposite side.

Given that sides A and B have a length of 2 units each and sides C and D have a length of 7 units each, and the angle between sides A and C is π/4, we can use trigonometry to find the height of the parallelogram.

Using the sine function, we can find the height (h) as follows: sin(π/4) = h/7 h = 7 * sin(π/4) h = 7 * (1/√2) h = (7√2) / 2

Now, we have the height of the parallelogram. To find the area, we multiply the base (2 units) by the height: Area = 2 * (7√2) / 2 Area = 7√2 square units.

So, the area of the parallelogram is 7√2 square units.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
