Question

The lenght and the breadth of a field are in the ratio 3:2 .the cost of levelling and turfing the field at the rate of 1.25 per sq.meter is 1470.find the cost of surrounding the field with the a fence at the rate of 2.50 per meter

Answer 1

Answer:

RS 4900

Step-by-step explanation:

area of the field = 1470÷1.25= 1176 sq. meter

let whole ratio be X

so the length Is 3x and breadth is 2x

we know 3X × 2X = 1176

6X = 1176

X = 196

length is 588 m

breadth is 392 m

perimeter of the field = 2× ( 588+392)

=1960m

cost of surrounding = 1960×2.50

= rs 4900
