As a engineer who was mechanical then electrical most buildings, schematics,etc require some form of calculation for some shapes seeing that those shapes are what make up the world. Say for example you need to make something like a mother board pro house knowing it's shape and angle helps make a more accurate structure during the blue printing and build phase. No one just goes in and wings it you need to determine angles for things you don't know that the point of it.

the boundary of a rectangular farm field in ireland has a straight rock wall along one side and fences along its other three sid
Inessa [10]

Answer:

781250 ft^{2}

Step-by-step explanation:

Let y is the length of the farm field

Let x is the width of the farm field

Given that, no fencing is necessary along the rock wall, so we can find the perimeter of the farm is:

2x + y = 2500 feet

<=> y = 2500 -2x

The are of the farm has the following formula:

A = x*y

<=> A = x(2500 - 2x)

<=> A = 2500x -2x^{2}

To have  the maximum area of field in square feet, we need to use differentials to estimate:

\frac{dA}{dx} = 2500 - 4x

Set \frac{dA}{dx} = 0, we have:

2500 - 4x  = 0

<=> x = 625 feet.

=> y = 2500 - 2*625 = 1250 feet

So the maximum area of field is:

A = x*y = 625*1250 = 781250 ft^{2}
