distance = 500 feet

Since Δ VWX and Δ YZX are similar then the ratios of corresponding sides are equal, that is

\frac{VW}{YZ} = \frac{VX}{YX} = \frac{WX}{ZX}

completing the required values gives

\frac{100}{l} = \frac{60}{30} ( cross- multiply )

60l = 30 × 100 = 3000 ( divide both sides by 60 )

l = 500

distance across the swamp is 500 feet
