Answer:
88 inches ^2
Step-by-step explanation:
Well find the side of a triangle first.
4*9=26
26/2=18
There are 4 identical triangles
18*4= 72
Now the bottom square
4*4=16
16+72= 88
88 inches ^2
36.64-21=15.64
15.64-6.14=9.5
The answer is she made $9.50 worth in local calls last month
Area= (3 √(3) × s^2) ÷ s
s= side length
area=(3 √(3) × 16^2) ÷ 16
area= 83.1384387633
