?How do I find the side length of a square with just an area?

Question

Well, I'm doing my summer Math homework and I just found a question that is knocking my brain dead. At first it looked really simple then I mixed up the problem by solving it with a S = P/4. So that accident got me confused. Here's the problem: Find the side length of a square that has an area of 169 square inches.

Please explain it within a sixth grader's understanding cuz I'n gonna b entering seventh.

Answer 1

okay... This is how u do it =]

you need to do it with nothing but the area of 169 right? so when you're using a square every side is the same... so do it backwards as if you're solving for area... length x width = area... so 169/2 = 1 side

hope this helps!

Answer 2

Look, area is calculated by squaring its side.

So, the area of a square with side of (say) 2 cm, would be 4 sq. cm.

Now, you've been given the area. Hence, you find the side of the square by finding the square root of the given area.

So square root of 169 = 13.

So the side of the square = 13 inches.

And there's the answer to your question! :)

Answer 3

This is an easier formula. S squared= Area

For you problem its S squared=169

You find the square root of 169 which is 13

Answer 4

you're using the wrong formula.

S=P/4 doesnt make use of the info given to you.

Area = S^2

you know the area, so take the square root to find S.

FYI: that's actually why they call it the square root - it came from the square.
