Explanation:
You would need to divide 75,000 by 100 to get how many minutes it would take to get to 75,000. You get 750 and after that, multiply it by 60 because there is 60 minutes in an hour.
The dimensions of the rectangle can be a length of 2ft and a width of 4ft.

How to find the dimensions of the garden?</h3>
Remember that for a rectangle of length L and width W, the perimeter is:
P = 2*(L + W)
And the area is:
A = L*W
In this case, we know that the area is 8 square feet and the perimeter is 12 ft, then we have a system of equations:
12ft = 2*(L + W)
8ft² = L*W
To solve this, we first need to isolate one of the variables in one of the equations, I will isolate L on the first one:
12ft/2 = L + W
6ft - W = L
Now we can replace that in the other equation to get:
8ft² = (6ft - W)*W
This is a quadratic equation:
-W^2 + 6ft*W - 8ft² = 0
The solutions are given by Bhaskara's formula:
![W = \frac{-6 \pm \sqrt{(6ft)^2 - 4*(-1)*(-8)} }{2*-1} \\\\W = \frac{-6 \pm 2}{-2}](https://tex.z-dn.net/?f=W%20%3D%20%5Cfrac%7B-6%20%5Cpm%20%5Csqrt%7B%286ft%29%5E2%20-%204%2A%28-1%29%2A%28-8%29%7D%20%7D%7B2%2A-1%7D%20%5C%5C%5C%5CW%20%3D%20%5Cfrac%7B-6%20%5Cpm%202%7D%7B-2%7D)
Then we have two solutions:
W = (-6 - 2)/-2 = 4ft
W = (-6 + 2)/-2 = 2ft
If we take any of these solutions, the length will be equal to the other solution.
So the dimensions of the rectangle can be a length of 2ft and a width of 4ft.
