bixtya [17]

Answer:

Follows are the solution to this question:

Step-by-step explanation:

In point A:

The two-point C and y is given, where C is the scale drawing lengths  and y is the actual mural lengths so, the formed equation is:  

\to \frac{c}{y}=\frac{2}{5}

In point C :

Using the value of the scale:

let  1 feet: 20 feet

therefore the equation is:

\to \frac{c}{y}=\frac{1}{20}

The size of c will be the length of:

\to c= \frac{y}{20}\\\\\to c= \frac{8}{20}\\\\\to c= 0.4\\

The diagram c scale width will be:

\to c= \frac{y}{20}\\\\\to c= \frac{15}{20}\\\\\to c= 0.75\\
