Formulas needed:
Square area = b^2
Rectangle area = bh
Triangle area = bh/2
Parallelogram = bh
Trapezoid area = a+b/2(h)
Rhombus area = pq/2
Even better; use online calculators.
To use these formulas, you need to substitute the values given for b,h,a,b,p or/and q and then solve to get area.
So for this example, since it's a rectangle, you use formula A = bh. Base is 5.1, and height is 6.
Substitute now.
A = bh
= (5.1)(6) (substitute)
= 30.6 (multiply)
Therefore the area is 30.6 m^2. Don't forget the unit measurements, which is *measurement*^2.
The experimental probability is what you actually rolled
24/60 = 2/5 = 40%
The theoretical probability is what we expect to happen
=number of even numbers / total number of numbers
3/6 = 1/2 = 50%
Area = Length × width
Area = 5/6 × 15/7 = 75/42 mi²
Area = 
There are a total of 33 students in the class (21+12=33). There are 12 boys in the class so the chance of drawing a boys name would be 12/33 which reduces to 4/11. This means you will draw a boys name 4 times for every 11 draws. To find the percent probability, just divide...
4/11 =.3636
multiply by 100 to convert to a percentage ( move decimal to the right 2 places).
.3636 = 36.36%
There is a 36.36% chance that a boys name is drawn.
