b) 144 square inches
Step-by-step explanation:
The complete question has 2 parts to answer:
a. What is the total length of the three fish?
b. How many square inches of water surface do the fish need?
Lets answer:
a)
The total length of three fish are the sum of all the individual fishes' length.
1st is 3.5 in
2nd is 5.5 inches
3rd is 3 inches
Sum is:
3.5 + 5.5 + 3 = <u>12 inches</u>
<u>f is 12</u>
<u></u>
b)
The expression gives the total area. We already found f = 12, now the area is:
Area = 12f
Area = 12 * 12
<u>Area = 144 sq. in.</u>
