Ascale drawing has a scale of 0.25 in : 12ft find the length on the drawing for an actual length of 15 ft.

Let the length on drawing for actual length of 15 ft = x inches

And they say that the ratio of drawing length to actual length is 0.25 in : 12 ft

it means we can make a ratio proportion such that

Cross multiplying we get

0.25 * 15 = 12*x

3.75 = 12 x

Divide both sides by 12

x = 0.3125

It means

the length on drawing for actual length of 15 ft = 0.3125 inches

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
