Use Pythagoras theorem. (a^2 + b^2 = c^2)

300^2+300^2 = 180000
√180000 = 424.3

The answer is 424 foot.

Hope this helps.

Answer:

Ratio of sweaters to dresses = 8 : 5

Sum of ratios = 13

Let number of sweater + dresses = x

$number \ of \ sweaters = \frac{8}{13} *x\\\\24 = \frac{8}{13}*x\\\\x = \frac{24*13}{8} = 3*13 = 39$

$number \ of \ dresses = 39 - 24 = 15$
