area=l*b

l=1.5x, b=x

A=1.5x*x=1.5xsquare.......eq 1

4rm d price

1sq meter will cost rs.5

dere4 x square meter will cost rs.480

(480*1)/5=96square meters

area=96.......eq 2

96=1.5x^2mspuare

x^2m=64; x=8

lenght =1.5*8=12; breadth =8

4 d height==> rs.3........1sq meter

den rs.360.........xsq meter

x=120square meter

let area= height*breadth

120=h*8

h=15m

dimension=12m by 8m by 15m
