The length of each side of the tiles is 7.2 in
<u>Explanation:</u>
Given:
Height of the tile, h = 3 in
Area of each tile, A = 21.6 in²
Length of each side, a = ?
We know:
A rhombus is a type of quadrilateral whose opposite sides are parallel and equal.Also, the opposite angles of a rhombus are equal and the diagonal intersect each other perpendicularly.
To find the area of a rhombus when the measures of its height and side length are given, use the formula
A = Base X height
21.6 in² = a X 3 in
a = 7.2 in
Therefore, the length of each side of the tiles is 7.2 in
we know that
A quadratic equation is a polynomial with an order of two. Its general form is
case a) 
<u>The case a) is a quadratic equation</u>
case b) 
<u>The case b) is a grade 
polynomial</u>
case c) 
<u>The case c) is a grade 
polynomial</u>
case d) 
<u>The case d) is a grade 
polynomial</u>
therefore
the answer is
34% of 150 is 51.
I hope this helps.
The problem statement tells you "7 friends were playing basketball".
_____
It appears 5 friends were only playing basketball, 2 friends were playing basketball and having snacks, and 3 friends were only having snacks. Apparently, 10 friends were doing neither of those activities.
