The scale of a map says that 2 cm represents 8 km. What is the actual number of kilometers that is represented by 3 centimeters on the map?​

The answer would be 12.

Step-by-step explanation:

I got 12 using the information we were given. Seeing as 8km is represented by 2cm, 1 cm would be 4km, right? (8 divided by 2 is 4.) So using that, we just need to multiply 4 by 3 to find what the 3km would be on the map.

3 ft

step-by-step explanation:

since the triangle is right use pythagoras' identity to solve for a

the square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

a² + 8² = ( )²

a² + 64 = 73 ( subtract 64 from both sides )

a² = 9 ( take the square root of both sides )

a = = 3

is there answer choices?
