Question

How many miles?? Please help me

Answer 1

33 miles

Explanation:

You will use the Pythagoras' theorem (
`a^2+b^2=c^2`)

Laura to her parents house is 'a', Her parents house to her grandparents house is 'c'

`a^2+b^2=c^2\\c^2-a^2=b^2\\65^2-56^2=b^2\\4225-3136=b^2\\1089=b^2\\b=√(1089) \\b=33`

Laura is 33 miles from her grandparents house
