# 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:

$a=1.52^{ 2 } = \dfrac{ 1444 }{ 625 } = 2 \ dm^2$
$b=(13268/100)^{ 2 } = 17604 \ dm^2$
$c=(562/10)^{ 2 } = \dfrac{ 78961 }{ 25 } = 3158 \ dm^2$
$d=(1.52 \cdot \ 10)^{ 2 } = \dfrac{ 5776 }{ 25 } = 231.04 \ dm^2$
