The both sides of the rectangle are :
- The length of the rectangle = 54 m.
- The breadth of the rectangle = 18 m.
Given :
- The length of a rectangle is thrice the breadth.
- The perimeter of the rectangle = 144 m.
To Find :
- The length and the breadth of the rectangle.
Solution :
Let,
The breadth of the rectangle be x.
The length of the rectangle be 3x because according to the question, the length of a rectangle is thrice the breadth of a rectangle.
Given,
Perimeter of the rectangle = 144 m
We know that,
Perimeter of the rectangle = 2(l + b)
Where,
• l = length.
• b = breadth.
Therefore,
So, the sides of the rectangle are :
★ The length = 3x = 3 × 18 m = 54 m.
★ The breadth = x = 18 m.
Hence,
The length and the breadth of the rectangle are 54 m and 18 m.
