The cost of fencing a circular field at the rate of Rs. 24 per metre is Rs. 5280. The field is to be ploughed at the rate of Rs. 0.50 per m2. Find the cost of ploughing the field (Take π = 22/7).


(REQUIRED QUALITY ANSWER)​

Answer 1

$\sf \large \underbrace{ \underline{ Understanding \: the \: Question}}$

As we know that fencing is always done at circumference and circumference of field is not given but cost of fencing of circumference is given to be Rs.5280 so we can easily find the circumference or circle by making equation as follow:

For Rs.24 length of fencing is 1m

$\sf \small For \: Rs. 5280 \: \: length \: \: of \: \: fencing \: \: is \: \cancel{\frac{1}{24} \times 5280}$

$\tt : \implies220m$

Hence the circumference of circle=220m

$\sf 2πr=220m$

$: \implies \sf 2 \times \frac{22}{7} \times r=220m$

$: \implies \sf r= \cancel{220m \times \frac{7}{22 \times 2} }$

$: \implies \sf r=35m$

So radius is 35m.

Now we have to find the area so that we can find the cost of ploughing.

★Area of circle=πr²

$\large\sf: \implies \frac{22}{7} \times {35} \times 35$

$\sf \large: \implies \: 3850m {}^{2}$

Cost of ploughing 1m²=Rs.0.5

Cost of ploughing 3850m²=3850×Rs.0.5

=Rs.1925

So required cost is Rs.1925

Step-by-step explanation:

what is fair ?

A fair is a gathering of people for a variety of entertainment or commercial activities. It is normally of the essence of a fair that it is temporary with scheduled times lasting from an afternoon to several weeks.

types of fair

-village fair

-temple fair

-travelling fun fair/ carnival

-street fair

-country fair

-trade fair

-festival

history of fair

The Roman fairs were holidays on which there was an intermission of labour and pleadings.In the Roman provinces of Judea and Syria Palaestina, Jewish rabbis prohibited Jews from participating in fairs in certain towns because the religious nature of the fairs contravened the prescribed practice of Judaism.

in the Middle Ages, many fairs developed as temporary markets and were especially important for long-distance and international trade, as wholesale traders travelled, sometimes for many days, to fairs where they could be sure to meet those they needed to buy from or sell to. Fairs were usually tied to special Christian religious occasions, such as the Saint's day of the local church. Stagshaw in England, is documented to have held annual fairs as early as 1293 consisting of the sales of animals. Along with the main fair held on 4 July, the city also hosted smaller fairs throughout the year where specific types of animals were sold, such as one for horses, one for lambs, and one for ewes.

fair's legacy

Fairs attracted great numbers of people and they often resulted in public order issues and sometimes riots. The holding of fairs was, therefore, granted by royal charter. Initially they were only allowed in towns and places where order could be maintained due to the presence of a bishop, sheriff or governor. Later various benefits were granted to specific fairs, such as the granting of a holiday status to a fair or protections against arrest for specific laws for the duration of the fair. Officials were authorised to mete out justice to those who attended their fair; this led to even the smallest fair having a court to adjudicate on offences and disputes arising within the fairground. These courts were called a pye powder court (from Old French pieds pouldres, literally "dusty feet", meaning an itinerant trader, from Medieval Latin pedes pulverosi).
