Answer:
16 square units
Explanation:
The area of a parallelogram is denoted by: A = bh, where b is the base and h is the height.
Here, we can see that the base is b = 4, but we don't know the height, which is the perpendicular distance between the top and bottom bases. To find it, notice that on the left, there's a right triangle, so we can use the Pythagorean Theorem to find the height:
h² = 5² - 3² = 25 - 9 = 16
h = √16 = 4
So, the height is 4. Plug this and the base value into the area formula:
A = bh
A = 4 * 4 = 16
The answer is 16 square units.
