The image contains two geometric objects, square and triangle
The square
The square has side equals to 12 cm
Find the area of the square
a = s × s
a = 12 × 12
a = 144 cm²
The triangle
The triangle has base equals to 12 cm, and the height equals to 17 - 12 = 5 cm
Find the area of the triangle
a = 1/2 × b × h
a = 1/2 × 12 × 5
a = 1/2 × 60
a = 30 cm²
Now add the area together
a = area of triangle + area of square
a = 144 + 30
a = 174
Answer:
The area is 174 cm²

In the situation, the number of bacterias are doubling for each sheet of paper cut, thus, the exponential equation for the puber is:
Initially, there was only one sheet of paper. Then, each sheet is cut in half, so we will have 2 sheets, then 4 sheets, then 8 sheets, and so on. That is, the number of sheets is continuously doubling, thus, the population after n cuts can be modeled by the following <u>exponential equation</u>:
