Answer 1

Answer: 1300*350=4,55,000m^2

Answer 2

$\underline{\underline{\mathfrak{\Large{Solution : }}}}\\ \\ \underline {\textsf {Given,}} \\ \\ \sf\:Perimeter = 1300 m \\ \\ \sf\:Length = 350 m \\ \\ \sf\:Perimeter = 1300 \\ \\ \sf\:1300 = 2 ( l + b)\\ \\ \sf\: 650 = 350 + b \\ \\ \large {\boxed {\sf { b = 300}}} \\ \\ \sf\: Area = l × b \\ \\ \sf\implies\: 350 × 300 \\ \\ \large{\boxed {\sf {Area \:= 105000\: m^2}}}$
