$\bold{\underline{\underline{Step-by-step\:explanation:}}}$

$\underline{\underline \bold{Given : }} \\ \implies \text{Length = 130 m }\\ \\ \implies \text{ Breadth = 95 m} \\ \\ \underline{\underline \bold{To \: Find : }} \\ \implies \text{ cost \: of \: fencing \: the \: field }= ?$

• According to given question :

$\bold{Finding \: perimeter \: of \: field : } \\ \implies perimeter \: of \: rectangle = 2(length + breadth) \\ \\ \implies perimeter = 2(130 +95) \\ \\ \implies \text{perimeter = 450 m} \\ \\ \bold{Cost \: of \: fencing \: 1 \: m \: ground = 20 \: rupees} \\ \implies Cost \: of \: fencing \: 450\: m = 20 \times 450 \\ \\ \therefore{ \text{ Cost \: of \: fencing \: 450 m =9000 rupees}}$
