Answer:
101
Step-by-step explanation:
Find the area of the left triangle
11 -8 = 3
A = l*w = 15*3 = 45
Then find the area of the right triangle
A = l*w = 8*7 = 56
Add the areas together
45+56 =101
The area of the yellow region is
Answer:

Step-by-step explanation:
Before calculating the scale we require the dimensions to be in the same units.
Using the conversion
1 yard = 3 ft and

The scale is then
2 in : 180 in ← divide both quantities by 2
= 1 : 90
=
