What I did was find the area of the figure as if it were a regular square.
Area = Length x Width
Area = 12 x 20
Area = 240
Then I find the area of the cut out piece, which happens to be a right triangle.
Area = 1/2(length x width)
Base/width = 20 - 14
Base/width = 6
Length = 12 - 10
Length = 2
Area = 1/2(2 x 14)
Area = 1/2(28)
Area = 14
Now subtract
240 - 14 = 226
226 should be your answer
Please correct me if I'm wrong xP
If Dave earns $150/week times 4 weeks = 600
3.8% commission on $4175.68 is $158.68
$600 + $158.68 = $758.68 for the month of February
First, look at the digits less than one one-hundredth (

, or .01):
0.00416
See if that number is closer to the higher or lower hundredth:
(if the first digit is 5 or greater, then higher;
if the first digit is 4 or lower, then lower)
Since 4 is closer to the lower hundred, round down
0.00416 -> 0.00000
Add this to the digits we didn't touch:
<span>17,546.32000 + 0.00000 = 17,546.32
</span>17,546.32416 rounded to the nearest hundredth is
