Answers
☆ Solution ☆
Given :-
The perimeter of the rectangular box is 60 m.
The length of the rectangular box is 10 m.
To Find :-
The area of the rectangular box.
Step-by-step-Explaination :-
Let,
The breadth of the rectangular box be b.
Now,
As we know that :-
Perimeter of the rectangle = 2 ( Length + Breadth )
Where,
The perimeter of the rectangular box = 60 m.
The length of the rectangular box = 10 m.
The breadth of the rectangular box = b.
Putting the respective value,
60 = 2 ( 10 + b )
60 = 20 + 2b
60/20 = 2b
30 = 2b
30/2 = b
15 = b
Hence,
The breadth of the rectangular box is 15 m.
Now,
As we know that :-
Area of the rectangle = Length × Breadth
Where,
The length of the rectangular box = 10 m.
The breadth of the rectangular box = 15 m.
Putting the respective value,
Area of the rectangle = 10 × 15
Area of the rectangle = 150
Hence,
The area of the rectangular box is 150 m².
Answer:
Using the formulas
A=wl
P=2(l+w)
Solving forA
A=Pl
2﹣l2=60·10
2﹣102=200m²
