Answer» FIRST we find area of FLOOR 5×3=15m^2 Now CARPET length= 0.5m(5dm=0.5m) Its area = LB = 0.5l = 15 L=15÷0.5=30m^2 Cost= area×cost per metre = 15× 350 = 5250

Answer»

FIRST we find area of FLOOR 5×3=15m^2

Now CARPET length= 0.5m(5dm=0.5m)

Its area = LB = 0.5l = 15

L=15÷0.5=30m^2

Cost= area×cost per metre = 15× 350 = 5250
