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


Result

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

Solution:

a=1.522=1444625=2 dm2a=1.52^{ 2 } = \dfrac{ 1444 }{ 625 } = 2 \ dm^2
b=(13268/100)2=17604 dm2b=(13268/100)^{ 2 } = 17604 \ dm^2
c=(562/10)2=7896125=3158 dm2c=(562/10)^{ 2 } = \dfrac{ 78961 }{ 25 } = 3158 \ dm^2
d=(1.52 10)2=577625=231.04 dm2d=(1.52 \cdot \ 10)^{ 2 } = \dfrac{ 5776 }{ 25 } = 231.04 \ dm^2
