A rectangle with an area of 32 inches squared has one side measuring 4 inches. A similar rectangle has an area of 288 inches squared. How long is the longer side in the larger rectangle?

Similar figures have corresponding sides, areas and perimeters in the same proportion.
32 : 288 = 4 : x
32/288 = 4/x
cross multiply
32x = 1152
x = ?
