Answer:
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.
3r + 2rt = 18
r is the common factor
r(3 + 2t) = 18
r= 18/ 3 + 2t
r= 6 + 9t
Hope this helps!
