Question

each side of a square measure 65m5dm.find it's area. by how many square meters does it fall short of a hectare​

Answer 1

Side of a square =65m5dm

1dm= 0.1 m

65m 5 dm = 65m + 0.1 * 5 m

= 65+0.5 m

= 65.5m

Area = side * side

= 65.5 * 65.5 m

= 4290.25 m2

1m2 = 0.0001 hectare

4290.25 m2= 0.0001* 4290.25 hectare

= 0.429025 hectare
