Answer 1

Answer:

Perimeter = 320 m

4 × length of the side of park = 320 m

Length of the side of park

»» 320/4 = 80m

Area = ( length of the side of park)²

= (80)²

= 6400 m²

hope it helps you.

Answer 2

Given: The perimeter of a square park is $320$m.

We have to find the area of the square park.

As we know that the formula to calculate the perimeter of the square is$P=4a$

Where a = side of the square.

We are solving in the following way:

We have,

$=>P=4a\\=>320=4a\\\\=>\frac{320}{4} =a\\\\=>a=80$

Solving the above equation we get,

The side of the square=$80m.$

As we know that the formula to calculate the area of the square is$A=a^{2}$.

The area of the square will be:

$=>A=a^{2}\\=>A=80^{2} \\=>A=6400$

Hence, the area of the square will be$6400m^{2}$.
