Answer 1

SOLUTION: The width of rectangular field is half its length. if its area is 512 sq. m find its perimeter. Question 927458: The width of rectangular field is half its length.

Answer 2

a rectangular field has an area of 18432 square meters . it's width is half as long as it's length.

Given,

Area of rectangle = 18432 m²

Area of rectangle = A= l × b

w = l/2   (given)

∴ Area of rectangle = A = l × l/2

18432 = l²/2

2 × 18432 = l²

l² = 36864

∴ l = 192 m.

w = l/2 = 192/2

∴ w = 96 m.

Perimeter of rectangle = P = 2 ( l + w )

P = 2 ( 192 + 96 )

= 2 ( 288 )

= 576

Therefore, the perimeter of rectangle is 576 m.
