Answer:
Step-by-step explanation:
The area of the square field = 5184 sq m.
Each side of the square field = 5184^0.5 = 72 m.
Perimeter of the square field = 4*72 = 288 m.
Perimeter of the rectangular field = 288 m.
Length of the rectangular field is 2B, where B = breadth of the field.
Hence 2(2B+B) = 288, or
3B = 288/2 = 144, or
B = 144/3 = 48 m so length = 2*48 = 96 m.
Area of the rectangular field = 96 * 48 = 4608 sq m.

Given:-
- ↦ Area of square field = 5184 m².
To Find:-
- ↦ Area of rectangle.
Formula to be used:-
- ↦ Perimeter of square = 4a
- ↦ Perimeter of rectangle = 2 (l + b)
Solution:-
- ↦ Let the side of square field as a.
Then,
- ⇒ a² = 5184 m²
- ⇒ a = √5184 m
- ⇒ a = 2 × 2 × 2 × 9 = 72 m
Now,
- ↦ Perimeter of square = 4a
- ↦ Perimeter of square = 4(72)
- ↦ Perimeter of square = 288 m
Now,
Perimeter of rectangle = 2 (l + b)
- ⇒ 288 = 2 (l + b)
As length is twice of its breadth,
- ⇒ 288 = 2 × (2b + b)
- ⇒ 288 = 2 × 3b
- ⇒ 288/2 = 3b
- ⇒ 144 = 3b
- ⇒ 144/3 = b
- ⇒ b = 48
Here, breadth is 48 m
Now length,
- ↦ Length = 2 × 48 = 96 m
Now, Area of rectangle ;
- ↦ Area of rectangle = l × b
- ↦ Area of rectangle = 96 × 48
- ↦ Area of rectangle = 4608 m².
✝ Hence, the Area of rectangle is 4608 m² ✝
