Answer:
The length in the draw is 10 cm
Step-by-step explanation:
step 1
Find the scale plan
Divide the width in the draw by the width in the real
so
[tex]\frac{4}{8}=\frac{1}{2}\frac{cm}{m}[/tex]
That means----> 1 cm in the draw is equal to 2 m in the real
step 2
Find the length in the draw
using proportion
[tex]\frac{1}{2}\frac{cm}{m}=\frac{x}{20}\frac{cm}{m}\\ \\x=20/2\\ \\x=10\ cm[/tex]
