What is 5'4 x 5' in square meters?

Answer 1

Let's start by measuring everything in the same units, rather than some in inches and some in feet.

(five feet + four inches) x (five feet)

= (sixty-four inches) x (sixty inches)

Now one inch is equal to 2.54 centimetres (this is one of those handy facts that's good to memorise), which means that

(sixty-four inches) = (sixty-four) * (2.54cm)

and

(sixty inches) = (sixty inches) * (2.54cm)

Further, a centimetre is 1/100 of a metre, so we write this as

(sixty-four inches) = (sixty-four) * (2.54cm) = (sixty-four) * (2.54) * (1/100 metre)

and

(sixty inches) = (sixty inches) * (2.54cm) = (sixty) * (2.54) * (1/100 metre)

So let's plug these two into our original equation, getting

(five feet + four inches) x (five feet)

= (sixty-four inches) x (sixty inches)

= (sixty-four) * (2.54) * (1/100 metre) * (sixty) * (2.54) * (1/100 metre).

All we have to do now is multiply, which gives us about 2.477 * (metre) * (metre) - a bit under two and a half square metres.
