Answer:
1380 in²
Step-by-step explanation:
The lateral surface is the sum of the areas of all the sides, or 'faces'.
The bases (the top and bottom) are <u>not </u>included.
This is a prism with triangles for bases (at each end). The sides are rectangles.
Add up the areas of the rectangles.
300 + 480 + 600 = 1380
The population of Saya islands after 4 months will be 8,100 people.
It is given in the question that:-
Initial population of Saya island = 100 people
The population of the Saya island tripled every month
We have to find the population of the island after 4 months.
The population of Saya island after 1 month = 100*3 = 300 people.
The population of Saya island after 2 months = 300*3 = 900 people.
The population of Saya island after 3rd months = 900*3 = 2,700 people.
The population of Saya island after 4th months = 2700*3 = 8,100 people.
