Given:-

length and breadth in ratio. 3:2

so,

let the length be 3x and breadth be 2x

so,

2(a + b) = perimeter

2(3x + 2x) = 350

10x = 350

x = 35

so,

length = 3 \times 35 = 105 \: m

breadth = 2x = 2 \times 35 = 70 \: m

for path,(as it is 3 meter wide from all side)

length = 105 - 2(3) = 99 \: m

breadth = 70 - 2(3) = 64 \: m

now,

ar(path)= ar(big \: rectange)- ar(small \: rectangle)

 = 105 \times 70 - (99 \times 64)

 = 1014 \:  {m}^{2}

cost of raving

=Rs. 105/m^2

so,

total \: cost \:  = total \: area \times cost \: per \:  {m}^{2}

 = 1014 \times 105

 = rs.\: 106,470

so,

Cost of raving=Rs 106470
