Squares

Calculate the area of square and result round to square decimeters.

a) a = 1,52 dm
b) a = 13 268mm
c) a = 562 cm
d) a = 1,52 m


Correct result:

a =  2 dm2
b =  17604 dm2
c =  3158 dm2
d =  231.04 dm2

Solution:

a=1.522=1444625 dm2=2 dm2
b=(13268/100)2=17604 dm2
c=(562/10)2=7896125 dm2=3158 dm2
d=(1.52 10)2=577625 dm2=231.04 dm2
