Step-by-step explanation:

Given,

Area of rectangle = 18432 m²

Area of rectangle = A= L × B

B= l/2   (given)

∴ Area of rectangle = A = L × l/2

18432 = L²/2

2 × 18432 = L²

L² = 36864

∴ L = 192 m.

B= L/2 = 192/2

∴ B= 96 m.

Perimeter of rectangle = P = 2( L + B )

P = 2( 192 + 96 )

= 2( 288 )

= 576

Therefore, the perimeter of rectangle is 576 m.
