Answer:
- 117 in²
Step-by-step explanation:
<u>Here are the steps on how we will solve this problem.</u>
- Step 1: Divide the shape into squares and rectangles.
- Step 2: Find the area of all squares and rectangles
- Step 3: Sum up all the areas to get your final answer.
Now, let's follow the steps. Please consider looking at the picture I uploaded. Looking at the picture, we can tell that the area is 70 + 32 + 15. Now, let's solve.
- 70 + 32 + 15
- => 102 + 15
- => 117 in²
Hence, the area of the shape is 117 in².
Recall your d = rt. distance = rate * time.
let's say the speed of the current is "c".
keeping in mind that, when the boat is going against the current, the boat is not really going at 2kmh, but instead at " 20 - c ", because the current is subtracting speed from it.
Likewise when is going with the current, is going at a speed of " 20 + c ".
if the boat took say "t" hours on the way over, on the way back it took the slack from the whole 8 hours and "t", namely it took " 8 - t " hours.
