The area is the sum of 'n' rectangle areas.
The width of the rectangle is size of interval, (domain size)/n
The height of each rectangle is f(interval) as interval moves along domain.
For this example, domain size = 3-1 = 2
size of interval = 2/n
height varies from f(1) to f(3), increasing by 2/n each time.
f(1+(2/n)i)
Putting this together, the area is the sum of:

Since you are given the function f(x). Sub input into f(x) to get area in terms of n and i.

Finally, the summation is:
Answer:
0.31
Step-by-step explanation:
1.2<u>4</u>5 rounds to 1.25
0.9<u>3</u>7 rounds to 0.94
1.25-0.94=0.31
Sua matemática seria:10.8 * 3 = 32.4
32.4 + 32.4 + 10.8 + 10.8 = 86.4
86.4 * 130 = 11,232
11,232 - 10,000 = 1,232Você precisará de mais 1,232 tijolos para concluí-lo.
Eu espero que isso ajude :)
