Question

A rectangular classroom is 12 meters long and 8 meters wide, you want to make a scale drawing of the room using a scale of 1cm:4 meters what will be the dimensions of your scale drawing?
A.) 48cm by 32cm
B.) 3 cm by 2cm
C.)8cm by 4cm
D.)6cm by4cm

Answer 1

Answer:

3 cm  by 2cm

Step-by-step explanation:

the scale drawing is smaller than the classroom

so  we take the ratio  1 cm : 4m   and multiply it to the dimensions.

(1 cm/4m )*  12 m =  3cm

(1 cm/4m )*  8  m=  2cm

classroom will be  3 cm long  and 2 cm wide

choice  B.
