Question

how much wire is needed to fence aap arc of length 12 m and breadth 10 M also find the cost of wire if the rate is rupees 8 per metrer​

Answer 1

Answer:

length ( l ) = 12 m

breadth ( b ) = 10 m.

perimeter =2( l x b )

                = 2 ( 12+10 )

                 = 2 x 22

                 = 44 m²

fenced with four rounds of wire = 44 x 4

                                                   = 176 m²

cost per m = 8

total cost = 8 x 176

                 = 1408rs
