A rectangular park measures 24mX18m. A path 2.4m wide is constructed all around it. Find the cost of paving the path with cement tiles of size 60cm X 40cm at the rate of $5.60 per tile ?

Correct result:

x =  5241.6 USD

Solution:

S1=24 18=432 S2=(24+2 2.4) (18+2 2.4)=656.64 S3=0.60 0.40=0.24 S=S2S1=656.64432=561625=224.64 n=S/S3=224.64/0.24=936 x=n 5.60=936 5.60=262085=262085 USD=5241.6 USD
