Answer:
43.5 cm² and 112 cm²
Step-by-step explanation:
Here the instructions aren't given what to do. So I am finding the area of the ∆s .
<u>Area </u><u>of</u><u> </u><u>first </u><u>∆</u><u> </u><u>:</u><u>-</u><u> </u>
- A = 1/2 * b * h
- A = 1/2 * 14.5 cm * 6cm
- A = 3 × 14.5 cm²
- A = 43.5 cm²
<u>Area </u><u>of</u><u> </u><u>second</u><u> </u><u>∆</u><u> </u><u>:</u><u>-</u><u> </u>
- A = 1/2 * ( sum of || sides) * h
- A = 1/2 * ( 9 cm + 19cm) * 8cm
- A = 4cm * 28cm
- A = 112 cm²
80 hours x 7.50=$600
3280 x 0.8=262.40
Total is $862.40 for the month
