Answer 1

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.
