As the flower bed is extended
2m 80cm+30cm=3m 10cm
area=s×s squnits 300cm+10cm=310cm
310×310=94100sqcm or 941sqm
Area before extending
2m 80cm =200cm+80=280cm
280×280=78400sqcm or 784sqm
Increase in area=941-784=157m or 15700cm
2m 80cm+30cm=3m 10cm
area=s×s squnits 300cm+10cm=310cm
310×310=94100sqcm or 941sqm
Area before extending
2m 80cm =200cm+80=280cm
280×280=78400sqcm or 784sqm
Increase in area=941-784=157m or 15700cm
