The total area would be the combined area of all three
Let’s knock out the first 2
4.5 * 13 = 58.5 * 2 = 117
Now the last
4.5 * 9 = 40.5
117 + 40.5 = 157.5 ft^2
Answer:
137 in.^2
Step-by-step explanation:
A = nsa/2
where
n = number of sides = 9
s = length of side = 4.7 in.
a = length of apothem = 6.5 in.
A = (9)(4.7 in.)(6.5 in.)/2
A = 137.475 in.^2
Answer: 137 in.^2
