Question

The perimeter of a square field is \[72\text{ }meters\]. Find the length of the side of the square.

Answer 1

Hint: Perimeter is equal to the sum of all the sides of the figure. Here we will use a formula for the perimeter of the square is equal to the sum of all the sides of the square. And as we know that the length of the square of all the four sides are equal. Perimeter is equal to the four times its sides.
$\therefore Perimeter\ \text{of square = 4}\times \text{sides}$

Complete answer:
Given that – The Perimeter of the square field is 72 meters
Perimeter of square =$4\times side$
Substitute the known values -
$\Rightarrow 72=4\times side$.
$\Rightarrow side=\frac{72}{4}$ [When multiplicative numerator changes its sides, it goes to the denominator]
$\Rightarrow side=18\text{ }meters$.
Therefore, the required solution is –
The length of the side of the square $=18\ \text{meters }$with the perimeter of a square field $72\,\text{meters}$

Note:: In such types of problems from menstruations where the final value is given and we need to calculate the asked dimension. At first, we get the exactly needed formula like here perimeter of square. Then we compare the formula after assigning the given values and finally we can calculate and find the required value. Always find the correlation between the known and unknown terms and calculate accordingly. One should be also very careful to write the units.
Each side of the square is equal and the perimeter of any polygon is the sum of its sides. So, if we take the length of each side of the square are sides(s) its perimeter will be equal to$s+s+s+s$. Which will be equal to\[4\times s\].So, the perimeter of the square will be\[4\times s\].
