Question

Determine the perimeter and area of the square whose side is: $90$m.

Answer 1

Step 1: Finding the perimeter of a square.

Side of square$=90$ cm.

And we know that, Perimeter of a square is $4\times \mathrm{side}$

$$\begin{gathered} =4\times 90 \\ =360 \end{gathered}$$

Perimeter of the square is $360$ m.

Step 2: Finding the area of square.

Area(A) of a square $=\mathrm{side}\times \mathrm{side}$

$$\begin{gathered} =90\times 90 \\ =8100 \end{gathered}$$

Area of square $=8100$m-sq.

Hence, the perimeter and area of square is $360$ m and $8100$ m square respectively.
