Step-by-step explanation:

Answer:

Step-by-step explanation:

area of rectangular mat= area of border

Step-by-step explanation:

Rectangular mat

length(l)=5m

breadth (b)= 3.5m

area of rectangular mat = l×b

=5×3.5

=17.5m2

Rectangular mat (with border)

length (l)=5m+1.8m=6.8m

breadth (b)=3.5m+1.8m=5.3m

area of rectangular mat with border=l×b

=6.8m×5.3m

=36.04m2

area of border=area of rectangular mat- area of rectangular mat with border

=17.5-36.04

=18.54m2

cost of 1m2=Rs.272

cost of 18.54m2=272×18.54

=Rs.5,042.88

Hence,the cost of border is Rs.5,042.88
