Answer:

306 m

Explanation:

distance between her house and the third point:

280 - 10 = 270 m

distance between the third point and the beach:

164 - 20 = 144 m

We have a right triangle ,then we can apply the Pythagorean theorem:

$\text{the distance between her house and the beach} =\sqrt{\left( 270\right)^(2) +\left( 144\right)^(2) } = 306\ m$
