Answer:
$5.16
Explanation:
Okay, so the first step is to move the decimal point of the 72% over to the left twice. Since it is a whole number, the decimal is at the back. So, the number went from 72 to .72.
After that, multiply 3.00 by .72 Like this:
3.00 * .72 = 2.16
The last step is to add the original number to that number. Like this:
3.00 + 2.16 = 5.16

The figure gives you numbers for "b" and "h". It gives you no angles, nor side lengths adjacent to a given angle. The only formula you CAN use is
.. A = (1/2)bh
Filling in the given values, you get
.. A = (1/2)*22*9
.. A = 99
Area of a triangle is always:
A=hb/2 (height*base)/2 in this case:
A=2*2/2=2cm^2
