A parallelogram has sides A, B, C, and D. Sides A and B have a length of #5 # and sides C and D have a length of # 4 #. If the angle between sides A and C is #pi/2 #, what is the area of the parallelogram?

Answer 1

#Area"_(ABCD) = 20# sq. units

If an interior angle of a parallelogram is #pi/2# then the parallelogram is a rectangle.

The area of a rectangle is the product of two adjacent sides.

In this case #4xx5=20#

To find the area of the parallelogram, you can use the formula: Area = base * height. In this case, the base can be either side A or side C, and the height is the perpendicular distance between side A and side C.

Since the angle between sides A and C is π/2, and side A has a length of 5, you can use side C as the base and side A as the height.

The area of the parallelogram is given by: Area = base * height = side C * side A = 4 * 5 = 20 square units.

So, the area of the parallelogram is 20 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.
