We can dig out the soil from the well equal to volume of well.
Height(h) of well is = 15 meters.
Diameter = 1.6 meters.
So radius(r) =

meter.
As well in cylindrical shapes.
So volume of well =

=

In general

So volume of well is =

cubic meter.
So we can dig out 30.144 cubic meter soil from well.
Perimeter of a rectangle can be represented by 2* length + 2 * width
We can represent the width with the variable x
We can represent the length by the expression 3x-1
So, now we can make a forumla and solve
2(3x-1) + 2(x) = 30
6x-2+2x = 30
8x = 32
x = 4 is the width of the rectange.
Now we find the length
3(4)-1
11 = Length
