Answer:
177.5 units
Explanation:
Let's denote the width of the cocoa farm as "w" and the length as "l". We know that the perimeter of a rectangle is the sum of all its sides, so we can set up the following equation:
2l + 2w = 497
We also know that the length is 5/2 times the width, so we can write:
l = (5/2)w
We can substitute this expression for "l" into the first equation and solve for "w":
2(5/2)w + 2w = 497
5w + 2w = 497
7w = 497
w = 71
So the width of the cocoa farm is 71. To find the length, we can use the expression we derived earlier:
l = (5/2)w = (5/2) * 71 = 177.5
Therefore, the length of the cocoa farm is 177.5.
