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
