Answer:
B. 99 square units
Step-by-step explanation:
The <em>parallelogram</em> is a quadrilateral where the opposite sides are parallel to each other. This geometric figure constitutes, therefore, a polygon that consists of 4 sides where there are two cases of parallel sides.
To calculate the area of a parallelogram, you must know the length of the height relative to one of its sides.
Let the base be the side x and the height (h) relative to the base. The area of the parallelogram is the product of the base and the height.
Where:
a is the area in square units.
x is the base in units.
h is the height in units.
Solving:
With x = 11 units and h = 9 units

<u>ANSWER: </u>
If x =
and x = -3 are the roots of the equation, then values of a and b are 3, -6
<u>SOLUTION:
</u>
Given, quadratic equation is
and its roots are -3 , 
We know that, for any quadratic equation of form
with roots
then,
Sum of roots
= 
Product of roots (
= 
Now, for given quadratic equation
= -3 and
= 
hence Sum of roots = 


on solving we get "a" = 3
Now product of roots = 

b = -6
hence, the values of a and b are 3, -6.
