Question

Oblicz pole prostokąta o bokach 125 mm i 3 dm . W dwóch jednostkach.( mm. i dm. )

Answer 1

a = 125mm = 1,25 dm

b = 3 dm

 

P=a*b

P=1,25dm*3dm

P=3,75dm.

 

 

 

a = 125mm

b = 300 mm

 

P= 125mm * 300mm

P= 37500mm.

 

Answer 2

10

3dm = 300mm

125mm * 300mm = 375mm = 37,5cm = 3,75dm
