Question

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

Answer 1

Given: Perimeter of square part$=320m$

We know that, perimeter of a square is four times the length of its side.
According to question,$4\times$ Length of the side of park $=320m$

Length of the side of park $=\frac{320}{4}=80m$
Lets evaluate area of the park,

Area $=$ Length of the side of park $\times$ Length of the side of park $=(80{)}^2=6400m^2$
Therefore, area of the square park is $6400m^2$.
