To evaluate u + xy, substituting the values u = 18, x = 10, and y = 8, we get:

u + xy = 18 + (10)(8)
u + xy = 18 + 80
u + xy = 98

The correct answer is 98.

To find the length of a side of the square field, we need to take the square root of the given area of 479 ft².

Taking the square root of 479, we get the approximate length of a side:

√479 ≈ 21.87 ft

Rounding to the nearest foot, the approximate length of a side of the field is 22 ft.

We round up to 22 ft because it is closer to the actual value of 21.87 ft than rounding down to 21 ft. This ensures that we don't underestimate the length and maintain a conservative estimate.
