Question

The length of a hall is 6 more than its breadth. If the perimeter of the
hall is 60 m, find the cost laying a carpet at the cost of * 15 per sq.m.​

Answer 1

Step-by-step explanation:

l=6+b

perimeter of rectangle=2(l+b) =60

2(6+b+b)=60

6+2b=30

2b=24

b=12

l=6+b=6+12=18

area of rectangle=l*b=18*12=216 sq. m

cost of 1sq.m=15

so cost of 216 sq. m=216*15=3240
