y | 450 | 362 | 305 | 268 | 245 | 156 | 0 |
The above graph represents the data given in a viewing window.
c.
To find: The area of the model in part ‘a’.
c.
Answer to Problem 46E
Area for the model in part ‘a’ is approximately 78750 square feet.
Explanation of Solution
Given:
x | 0 | 50 | 100 | `150 | 200 | 250 | 300 |
y | 450 | 362 | 305 | 268 | 245 | 156 | 0 |
Calculation:
From the graph of part ‘b’,
Width of rectangle is
Height of rectangle is
The Area is,
Thus we can estimate the area of the plot of land.
