Answer:

75

Step-by-step explanation:

Area of a triangle is <em>l </em>x <em>w </em>(length x width)

That's 4 cm x 12 cm. Now you could go ahead and figure it out from there, but you have to remember it wants the answer in meters. It tells us that for every 4cm, it is 5m. The easiest way to figure this out is to convert to meters before multiplying. Since 4 cm is 5m, the <em>l </em>becomes 5m. 4 goes into 12 three times. So we would do 5 x 3 to get 15m for the new <em>w. </em>Now we can solve for area.

<em>l </em>x <em>w </em>= A

5m x 15m = A

75m = A

I hope this helped :)

A rectangular plot of farmland will be bounded on one side by a river and on the other three sides by a​ single-strand electric
Murrr4er [49]

Answer:

A = 781250\,m^{2}, x = 625\,m, y = 1250\,m

Step-by-step explanation:

The perimeter covered by the electric fence in meters is:

2\cdot x + y = 2500

The area of the rectangle is:

A = x\cdot y

A = x \cdot (2500-2\cdot x)

Let differentiate the previous equation and equates to zero:

2500-4\cdot x = 0

The critical point is:

x = 625\,m

By the Second Derivative Text, it is proved that critical point lead to a maximum:

\frac{d^{2}A}{dx^{2}} = -4

The other side of the rectangle is:

y = 1250\,m

The largest area than can be enclosed is:

A = (625\,m)\cdot (1250\,m)

A = 781250\,m^{2}

The dimensions of the triangle are:

x = 625\,m

y = 1250\,m
