Answer:

Explanation:
Let's just do the green triangle, so I don't spoil the fun of the whole worksheet.
Here you would use the Pythagorean Theorem to solve this. We know that 3 squares is 300km, so 1 square is 100km.
It is 6 wide, and 6 tall.
a^2+b^2=c^2 => 6^2 + 6^2 = h^2
c is the hypotenuse, a and b are the legs, interchangeable.
72 = h^2
Square root both sides and get:

you can plug this into calculator to get final answer or simplify it.

root 36 is equal to 6 so we can write it as...

Repeat this for the rest of the assignment. I believe you can do it!
