Answer :
Breadth = 30 m
area of the rectangle = 2700 m²
Explanation :
⋆Given :
↦Perimeter = 240 m
↦Length = 90 m
i) Breadth
Solution :-
↬ Perimeter of a rectangle = 2 ( l + b )
↬ 240 = 2(90 + b)
↬ 240 = 180 + 2b
↬ 240 - 180 = 2b
↬ = b
↬ 30m = b
(ii) Area of a rectangle
Solution :-
↬ Area of a rectangle = l × b
↬ Area of a rectangle = 90 m × 30 m
↬ Area of a rectangle = 2700 m²
