Answer:
Part A: 115
Part B: 36000
Explanation:
Part A asks for the perimeter, which is adding, so add up the 15, 40, and 60, which will equal to 115.
Part B asks for the area, which is multiplying, so you multiply the numbers,
15 x 40 x 60 = <u>36000</u>
15 x 40 = 600
600 x 60 = 36000
You could try multiplying it a different way but get the same answer:
60 x 40 x 15 = <u>36000</u>
60 x 40 = 2400
2400 x 15 = 36000
I'm not sure if this is correct but I hope I helped

The simplest way to evaluate the sum is to substitute k = 3, 4, 5, 6 into each term and sum them
(- 9 + 20) + (- 12 + 20) + (- 15 + 20) + (- 18 + 20)
= 11 + 8 + 5 + 2 = 26
