hi, do you know to find the length of a diagonal if the area is given but not the sides? For example, I got asked in a problem to find the diagonal across a square if the area is 22,500 ft and I have to round that answer to the nearest foot. what do i do to solve the problem??
I prefer using the constant approach; d = s / 0.70711 or if you must ... d = s / (sqrt(2)/2) s = d * 0.70711 or again s = d * (sqrt(2)/2) for rough lumber or metal work where approximation is acceptable, we say s is roughly 71% of d d is roughly 142% of s
Wish it was explained in layman's terms, I was ok until you started using words that are alien to me like for instance hopomoss (I know that's wrong but I cant remember the actual word and that's the first time I've heard it). I am trying to work out the measurement of a diagonal corner to corner line on a square 60x60cm. I didn't realise it was such a complicated method. I was confused by the 90* angle because some squares can be a mile square and some can be just an inch square, more I think about it the more confused I get. Thanks anyway.
@ bridgit that is easy. The area of a square is : a × b =A. Since a=b I.e its a square. Divide the area by 2 and you will find the length of one of the sides. I.e a=A/2
I tried really hard to understand this, but I got totally confused because I'm trying to take in these new words I don't know. I can do sums about money, even translating from imperial to metric as in £'s shillings and pence and £'s and pence. I worked with money for more than 60 years, but this kind of sums is a whole new ball game. I thought it would be a simple formula to measure corner to corner of a square. It was so complicated like a different language. It will be a lot easier to cut a 3' x 3' square then measure a line between two furthest corners, which is how I've tackled these problems in the past, but I thought I'd look for a magical formula.
Definitely simpler than squaring , adding and then taking roots ..Never occured to me b4 .
a perfect mathematician

A/2 times sq root of 2 = side
I prefer using the constant approach;
d = s / 0.70711 or if you must ...
d = s / (sqrt(2)/2)
s = d * 0.70711 or again
s = d * (sqrt(2)/2)
for rough lumber or metal work where approximation is acceptable, we say
s is roughly 71% of d
d is roughly 142% of s
(9x9)+(9x9)=162 then the square root.= works for me
Nice, but it does require squaring a root, which most people can't do without a calculator. Division and multiplication most people can do.
THANK YOU MY DUDE
How bout putting it in simpler terms for us dummies that have no clue what your talking about lol
Clear as mud

NOOOOO IDIOT
Thanks DUDE :)
Y'all from squaresville.
Right but you didn't figure the answer???
what the sides of my square are not all the same?
Then it's not a square
