Question

5.1 m^2 = ??? cm^2 5.1 meters squared is equivalent to how many centimeters squared?

Answer 1

$1m=100cm \implies 1m^2=10000cm^2 \implies 5.1m^2=51000cm^2$

Answer 2

we know that

$1m=100cm$

now, we can square both sides

$(1m)^2=(100cm)^2$

$1m^2=10000cm^2$

we are given

$=5.1m^2$

now, we can write it as

$5.1m^2=5.1*1m^2$

we can replace 1m^2

we get

$5.1m^2=5.1*10000cm^2$

we get

$5.1m^2=51000cm^2$.............Answer
