Grade7_G_Scale Drawings

A scale drawing of a rectangular park is 5 inches wide and 7 inches long. The actual park is 280 yards long. What is the area of the actual park, in square yards?

Here is a polygon. Draw a scaled copy of the polygon using a scale factor of $$\frac{1}{2}$$ .

The scale of a map says that 4 cm represents 5 km.

(a)   cm on the map represents an actual distance of 10 km.

The scale of a map says that 4 cm represents 5 km.

10 cm on the map represents an actual distance of (a)   km.

Tyler has two different maps of Ohio.

• - On the first map, the scale is 1 cm to 10 km. The distance from Cleveland to Cincinnati is 40 cm.

• - On the second map, the scale is 1 cm to 50 km.

The distance from Cleveland to Cincinnati on the second map is (a)   cm.

True or False: Scaled copies have congruent angles.

True or False: If using a scale factor of 3, the perimeter of a scaled copy is triple the perimeter of the original copy.

True or False: If using a scale factor of 3, the area of a scaled copy is triple the area of the original copy.
