Area of a triangle = ½ * base * height
Area of blue triangle = ½ * 4 * 4
Area of blue triangle = 8
Area of red triangle = ½ * 4 * 3
Area of red triangle = 6
TOTAL AREA = 8 + 6 = 14
The area is 31.5 units squared
I’m not sure but if I’m right Jen it will be 1 two dollar toy and 5 five dollar toy

Answer:
19 hours
Step-by-step explanation:
You have 279. First, devide the 279 by 9(dollar amount).
279/9 = 31
So combined they work 31 hours. Subtract 7 from this, since we know Katya worked 7 extra hours. Youll now have 24. (31-7 = 24)
Next, divide this number in half, which will get you what they both worked before Katya worked an extra 7 hours.
24/2 = 12.
Now that we know they both worked 12 hours, we can just add back the 7 hours Katya worked.
12+7 = 19.
So the answer to how many hours katya worked will be:
<u>19 hours</u>
