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

Answer: C. How many mountain ranges are in the U.S.
Step-by-step explanation:
A statistical question first of all has to have a quantitative response i.e., answers should be in numbers.
The only two questions here that would yield a numeric answer are options C and D.
Furthermore, a statistical question has variability in it which means that the answer is based on multiple observations not just one. The observations in option C are mountain ranges and as the question requires finding out details about multiple mountain ranges, this is a statistical question.
This is opposed to option D which addresses issues surrounding just one mountain.
