A rectangular field has an area of 1 comma 764 m squared The width of the field is 13 m more than the length. What is the perimeter of the field?

Let the length be x meters, so the width is x + 13. The area gives x(x + 13) = 1,764, which factors as (x − 36)(x + 49) = 0; the positive length is 36 m, so the width is 49 m. The perimeter is 2(36 + 49) = 170 m, so the correct choice is A, 170 m.
