You are building a new extension and are looking at the plans.referring to the scale, what is the actual measurement of the wall marked 18 cm on the plan?m

Respuesta :

we have that

The scale is equal to [tex]\frac{1}{50}[/tex]

That means

[tex]1\ cm\ in \ the \ plan=50\ cm\ in \ the \ actual[/tex]

so

by proportion

Find the actual measurement of the wall marked [tex]18[/tex]cm on the plan

[tex]\frac{1}{50}\frac{plan}{actual}=\frac{18}{x}\frac{plan}{actual}\\ \\x=18*50\\ \\x=900\ cm[/tex]

Convert to meters

[tex]900\ cm=900/100=9\ m[/tex]

therefore

the answer is

[tex]9\ m[/tex]
