a map of 5 inches represents 200 miles of actual distance suppose the distance between two cities on the map is 7 inches what is the actual distance between the two cities write the rule you used to find the actual distance

280 miles

Step-by-step explanation:

200/5=40 (we do that to find how much each inch is)

40 x 7=280

look a the sides they are perpendicular

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
