Question

For exercises 5-6, suppose you are making a scale drawing. Find the length of each object on the scale drawing with the given scale. 5) A parking lot 460 meters wide; 1 centimeter = 16.5 meters. 6) A desk 7.5 feet long; 1.5 inches = 0.5 feet.

Answer 1

8 88 cm

5.625 inches

Explanation:

The length scale drawing of the given object :

5) A parking lot 460 meters wide;

1 centimeter = 16.5 meters.

1 cm on the drawing is equivalent to 16.5 m on ground

Hence, using cross multiplication :

If :

1 cm = 16.5 m

x = 460 m

Cross multiply :

16.5x = 460 * 1

x = 460 / 16.5

x = 8.88 cm

6) A desk 7.5 feet long; .

Scale = 1.5 inches = 0.5 feet

1.5 inches on map is equivalent to 0.5 feets on ground

1.5 inch = 0.5ft

x in = 7.5 feets

Using cross multiplication

0.5x = 1.5 * 7.5

0.5x = 11.25

x = 11.25 / 0.5

x = 5.625 inches
