if u answer this i will mark u as brainliest

Answer 1

Answer:

perimeter of a rectangle=2(l+b)

2(78+56)

=190

cost of fencing= 190×50

=5,678

Answer 2

Answer:

$lenght \: of \: rctanguar \: field \: = 78m \\ breadth \: of \: rectnguar \: field \: = 56m \\ total \: perimeter \: of \: field \: = 2 \times (lenght \: + \: breadth) \\ =2( 78m + 56m) \\ = 156m + 112m \\ = 268m \\ now \: cost \: of \: fencing \: per \: 1m \: is \: = 50rs \\ so \: cost \: of \: fencing \: of \: 268m \: of \: lenght \: = 268 \times 50rs = 1340rs$
