Question

Find the area of a square park whose perimeter is $320m$

Answer 1

Step 1: Solve for the side of the square park:

Let the length of the side of the park be $xm$

The perimeter of the square$=4\times \left(lengthofside\right)$

$=4xm$

Substituting the given value we get

$\Rightarrow$$320=4x$

$\Rightarrow$$x=80m$

Step 2: Calculate the area of the square park

Area of the square$={\left(lengthofside\right)}^2$

$\Rightarrow$ $=x^2$

$\Rightarrow$ $={80}^2$

$\Rightarrow$Area of the square $=6400m^2$.

Hence the area of the square park is $6400m^2$.
