3.9 / 11.7 = 16.5 / x Multiply both sides by x
3.9 * x / 11.7 = 16.5 * x / x
3.9 x / 11.7 = 16.5 Multiply both sides by 11.7
3.9 x * 11.7 / 11.7 = 16.5 * 11.7
3.9 x = 193.05 Divide both sides by 3.9
3.9 x / 3.9 = 193.05 / 3.9
x = 49.5 ft
OR
11.7 = 3.9 * 3
So :
3. 9 / 11.7 = 3.9 / ( 3.9 * 3 ) = 1 / 3
16. 5 / x = 1 / 3 Multiply both sides by x
16.5 * x / x = 1 * x / 3
16.5 = x / 3 Multiply both sides by 3
16.5 * 3 = x * 3 / 3
49.5 = x
x = 49.5 ft
