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

3 cm by 2cm

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
