C. 34.081 sin (0.888 x + 1.341) + 82.822
Step-by-step explanation:
I calculated it logically
Given:
The perimeter of a rectangular building is 1200 feet.
The width of the building is 2 feet less than three times the length.
To find:
Width of the building.
Solution:
Let length of the building be x.
Then, width = 3x-2
We know that,




Add 4 on both sides

Divide both sides by 8.


Now,




Therefore, the width of the building is 449.5 feet.
7(3 + 9) = 7(3) + 7(9) = 21 + 63
