Given :
Length and breadth of rectangle = 5 : 3
Perimeter of rectangle = 840m
To find :
Area of the rectangle.
Solution :
Here,
Length = 5x
Length = 5xBreadth = 3x
Using the formula Perimeter = 2(l+b)
Thus, x = 52.5
So, length and breadth are :-
- 5x = 5 × 52.5 = 262.5
- 3x = 3 × 52.5 = 157.5
Hence, Length = 262.5m and breadth = 157.5m.
Now, Area :
Therefore, Area of the rectangle is 41,343.75m².
