This is a scale drawing of an apartment. The actual apartment has a perimeter of 160 ft. Draw another scale drawing of the apartment using the scale 20 ft to 1 unit from the apartment to the drawing. EXPLAIN your reasoning.

Step-by-step explanation:

As the perimeter lies along the edges of squares and we count 16 sides of squares as we work around the perimeter, this means that each square is

160 / 16 = 10 ft on a side.

so 10 ft in real life plots to 1 unit on the drawing

If the scale is changed to 20 :1 , then the drawing would be exactly the same shape, only each side would have half the original drawing units.

In stead of a 40 ft side being represented by 40 ft / 10 ft/unit = 4 units, That side would be 40 ft / 20 ft/unit = 2 units

answer: 5

step-by-step explanation:

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
