Answer 1

First change the km in my that is 1.5×1000= 1500 m perimeter=length ×breadth So,perimeter=1500×90=135000 area in hectares is 13.5

Answer 2

$hey \: mate \\ here \: is \: your \: answer \\ \\ the \: perimeter \: of \: rectangle \: is \: \\ 2(l + b) \\ l = 1.5km \: first \: convert \: into \: \: \\ meter \: so \: 1.5 \times 1000 = 1500ms \\ using \: formula \\ 2(1500 + 90) \\ 2(1590) = 3180ms \\ = .318 \: hectares$
