Question

If the length of the side of a square is 11cm. Then find its area and also find the total length of its boundary.​

Answer 1

Answer:

$\displaystyle 44\:cm. = P \\ 121\:cm.^2 = A$

Step-by-step explanation:

All angles and edges are congruent in a square, so first, find the total boundary by multiplying the length of the edge by 4:

$\displaystyle 4l = P \\ 4[11] = P \\ \\ 44 = P$

Now, for the area, you square the length of the edge:

$\displaystyle s^2 = A \\ 11^2 = A \\ \\ 121 = A$
