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
She swims for 2.5 hours at a rate of 2 km/hr
Multiply 2.5 * 2 = 5 km
Answer:
(4 + 2√5) i
Step-by-step explanation:
√(-16) + √(-25 + 5)
√(-16) + √(-20)
4i + 2i√5
(4 + 2√5) i
