Question

A rectangular garden 63 m long and 54 m broad has a
path 3 m wide inside it. Find the cost of paving the path
at Rs. 37/2 per square metre:​

Answer 1

Area of rectangle (outer)

IXb=63x54=3402m2

Area of inner rectangle

I=57, b = 48

Area = 57x48=2736m2

Area of Path=3402-2736 = 666m2

cost of paving

666x37/2=333x37=Rs.12321

Answer 2

given length l= 63m

breadth b= 54m

area of the rectangular plot= 63*54

=3402

path of 3m inside it

therefore length is=(63-3-3)m

=57m

breadth=(54-3-3)m

=48m

area of the inside rectangle=57*48

=2736

area of the path=(3402-2736)

=666

cost of paving the road is =666*37/2

= 12321
