Answer 2

Step-by-step explanation:

Given

Area the square field is twice that of a rectangular field

Let a be the side of the square

• length of the rectangular field ( l ) = 169 m
• width of the rectangular field ( b ) = 50 m

$\boxed{ 2a^2 = l × b}$

= 2a² = 169 × 50

= a² = 169 × 25

= a = 13 × 5

= a = 65 m
