Question

we want to put a fence around a rectangular plot.The fence costs $50 per meter.The length and width of the plot are in the ratio 2:1.The total cost of the fencing comes out to be$1500.​

Answer 1

Answer:

Length of plot is 10m.

Width of plot is 5meter.

Step-by-step explanation:

The ratio of length and widthof the plot is 2:1

So, let the width be $x$.

Therefore the length is$2x$

Perimeter of the rectangular plot is:

2×(length+width)=$2(x+2x)=2(3x)=6x$.

Cost of fencing per meter is $50.

Therefore total cost of fencing the rectangular plot is=$6x$×$50.

It is given that total cost of fencing is $1500.

Therefore,

6X×$50=$1500

$300x=1500\\x=\frac{1500}{300} =5$

Thus the width of the plot is 5meter and the length is 10meter.
