Width is 18 inches

Perimeter is 99 inches

Area is 567 square inches

Step-by-step explanation:

The ratio of width to length is 4 : 7

The length is 31.5 inches

The width = (31.5 * 4) : 7 = 18 inches

Perimeter = 2 (length + width)

Perimeter = 2 (31.5 + 18) inches = 99 inches

Area = length * width

Area = 31.5 inches * 18 inches = 576 square inches.
