A rectangular garden measuring 30 m by 35 m bordered (and surrounded) by a fence. Inside, a walk that is 4 m wide goes all the way along the fence Find the area of this walk . Be sure to include the correct unit in your answer Please help please :

Look at each side of the yard separately.

On one side the walk is 4 ft by 49 ft. On the opposite side it is the same. On the other ends the walk is also 4 ft wide but it's length is not 37 ft, it is 37–4-4, which is 29 ft. Those 4 ft subtractions are for the walk that is already on the first two sides. So the area of your walk is

2×4×49 + 2×4×29 = 392+232= 624 sq ft

The Second choice is correct
