we know that
[tex] 1m=100cm [/tex]
now, we can square both sides
[tex] (1m)^2=(100cm)^2 [/tex]
[tex] 1m^2=10000cm^2 [/tex]
we are given
[tex] =5.1m^2 [/tex]
now, we can write it as
[tex] 5.1m^2=5.1*1m^2 [/tex]
we can replace 1m^2
we get
[tex] 5.1m^2=5.1*10000cm^2 [/tex]
we get
[tex] 5.1m^2=51000cm^2 [/tex].............Answer
