The cost of ploughing a square plot at the rate of Rs. 7 per square metre is Rs. 1008. The cost of fencing its boundary at the rate of Rs. 5 per metre is =?

Answer 1

Answer:

hi mark me as brainlist

Step-by-step explanation:

Answer: 240 rs.

Step-by-step explanation:

area of plot = total rate for ploughing/ rate of per square plat = 1008/7= 144 square metre

area of square plot = (side * side)= 144 square metre

so side will be \sqrt{144}

144

= 12 metre

now length of fencing its boundary = perimeter of the plot = (4* side)

4* 12= 48 metres

cost of fencing = rs. 5/metre

complete cost of fencing its boundary will be = (perimeter of plot * rate per metre) = 48 *5 = 240 rs.

Answer 2

Answer:

180

Step-by-step explanation:

One SQ meter is 7 RS

1008÷7 = 144

the plot is 144 SQ meters, Meaning 144 ÷ 4 = border lengths=36 meters each side

36 × 5 = 180
