Enter one known value and calculate the side, area, perimeter or diagonal of a square. You will get solution with step-by-step explanation.
To calculate missing value in square, based on one known value, you need to remember just three formulas.
F1: | $$ P = 4 \cdot a $$ |
a = side d = diagonal A = area P = perimeter |
F2: | $$ A = a^2 $$ | |
F3: | $$ d = a \cdot \sqrt{2} $$ |
The diagram at the right shows when to use each of these formulas.
If you are given diagonal d and you want to calculate side a, then you need to use formula which connects d and a.
If you are given area A and you want to calculate perimeter P then you need to make two steps to calculate perimeter. In first step you apply formula which connects area A and side a after that use formula which connects side a and perimeter P.
