# 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:

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