1. here is a scale drawing of a swimming pool where 1 cm represents 1 m.

a. how long and how wide is the actual swimming pool?

b. will a scale drawing where 1 cm represents 2 m be larger or smaller than this drawing?

c. make a scale drawing of the swimming pool where 1 cm represents 2m.

A. 10 m wide and 20 m long

B. Smaller

C. 5 cm wide and 10 cm long

Step-by-step explanation:

Suppose that the scale drawing of a swimming pool is 10 cm wide and 20 cm long (see first figure attached).

A

If  1 cm represents 1 m, then 10 cm represents 10 meters and 20 cm represents 20 meters. So, the actual long of the swimming pool is 20 m and the actual wide is 10 m.

B

Knowing that 1 cm represents 2 m, then the next proportion let us calculate how many cm represent 10 m.

1/2 = x/10

(1/2)*10 = x

5 = x

So, 5 cm represents 10 m. In the same way, we can get that 10 cm represents 20 m. Consequently, the new draw will be smaller.

In general, because now 1 cm represents more meters, there less centimeters are needed to represent the same meters as before.

C

See the second figure attached.
