<u>Answer:</u>
Area of kite is 30 sq units.
<u>Solution:</u>
Note: Refer the image attached
From the given,
AC = 10 ; BD = 6
Kite is a quadrilateral as it has two equal adjacent sides.
The formula for the area of quadrilateral (kite) when both the diagonals are given is

Here AC is
and BD is 
On substituting the given values we get

Answer:
infinatly many solutions
Step-by-step explanation:
x can equal anything and still be correct.
The right equations are a+c=30 (total number of people) and 8a+c=100 (total amount of money). So answers B and D cannot be right.
a+c=30 can be rewritten as c=30-a and filled into the second one:
8a + 30-a = 100 => 7a = 70 => a=10
That leaves answer A as the right one.
