Algebra 1 and Geometry help?

Question

If the surface area of a square is 9 sq. units, what is the perimeter of the square? Please explain how you got the answer!!!

also, what are some basic geometry pointers? what about algebra 1 graphing(ie parabola, inequalities, etc.) tips? i have a test for geometry readiness tomorrow, and i'd like to be prepared, and i've forgotten almost all of the lessons on graphing and haven't taken geometry yet! thanks.

Answer 1

each side of this square is  3 units long [ since the area of a square is s^2]

so a square has 4 sides = 3*4 = 12 units

study is my tip for you...

Answer 2

area of a sq. = s^2

a = s^2

9 = s^2

s =3

p = 4s

p = 12

from algebra 1, just remember to do opperations on both sides of the equation. for geometry, try to memorize basic area/ volume equations if you aren't given them on the test.
