Please mark me as the Brainliest

Step-by-step explanation:

Perimeter of Square = 4a = 400 m

a = 100 m

Side of the Square (a) = 100 m

Area of Square = a² = (100)² = 10000 m²

Area of square park is 10,000 m²

Answer 2

Answer:

$\sf \: perimeter \: of \: square \: = 400m \\ \sf \: 4 \times side = 400 \\ \sf \: side = \cancel \frac{400}{4} \\ {\boxed {\color{purple}\sf \: \: side \: = 100m }} \\ \\ \sf \: area \: of \: square \: = side \times side \\ \sf \: = 100 \times 100 {m}^{2} \ \: \\ \sf \: = 10000 {m}^{2} \\ \\ \boxed{ \color{red}\sf \: area \: = 10000 {m}^{2} }$
