Question

Calculati:

a) in m2 ( metri patrati ) :
24 dam2 + 36,25 hm2 + 275 m2=
92,30 m2 + 276 325 cm2 + 48 dm2=
326,25 dam2 - 0,72 hm2=
2,75 m2 - 32,25 dm2=
b) in cm2 ( metri patrati ) :
7,25 m2 - 4,52 dm2 + 72,5 cm2

Answer 1

A) 2400 m2 + 362500 m2 + 275m2
 = 365175 m2

92,30 m2 + 27,6325m2 + 0,48m2
= 120,412 m2
 
32625m2 - 7200m2
= 25425 m2

2,75m2 - 3225m2
= minus 3222

b) 72500cm2 - 452cm2 + 72,5 cm2
 =72120,5 cm2
