Question

If 1 inch is 2.54cm. How many squared inches are there in 7.55 squared meters?

Answer 1

`11702.5` squared inches.

Explanation:

As `1` inch = `2.54cm.` i.e. `0.0254` meters

`1` squared inch is `0.0254xx0.0254=0.00064516` `m^2`

i.e. `1` `m^2` is `1/0.00064516=1550` squared inch

and `7.55` `m^2` is `7.55xx1550=11702.5` squared inches.

Answer 2

Around `11703` squared inches.

Explanation:

We have:

`1 \ "inch"=2.54 \ "cm"`

Also, `1 \ "m"=100 \ "cm"`.

`:.1 \ "inch"=0.0254 \ "m"`

`<=>(1 \ "inch")^2=(0.0254 \ "m")^2`

`1 \ "inch"^2=0.00064516 \ "m"^2`

Therefore, in `7.55 \ "m"^2`, we have:

`(7.55color(red)cancelcolor(black)("m"^2))/(0.00064516color(red)cancelcolor(black)("m"^2)\"/inch"^2)=11702.5234 \ "inch"^2`
