4 meters is the width of the pathway.

Step-by-step explanation:

Given that,

Length = 350m

Width = 200m

The total area of the pathway = 74,464m sq.

Let the width of the pathway be x giving the equation

(350 + 2x) (200 + 2x)

As we know that,

A = l * w

74,464 = (350 + 2x) (200 + 2x)

74,464 = 70,000 + 700x + 400x + 4x^2

74,464 - 74,464 = 4x^2 + 1100x - 4464

0 = 4(x^2 + 275x - 1116)

0 = 4(x-4) (x + 279)

∵ x = 4 or x = - 279

A negative number cannot be the width. So, the width of the pathway is 4meters.
