we know that
[scale]=[blueprint]/[actual]-------> [actual]=[blueprint]/[scale]
[scale]=3/5 in/ft
for [wall blueprint]=18 in
[wall actual]=[wall blueprint]/[scale]-------> 18/(3/5)----> 30 ft
Part A)
the actual wall is 30 ft long
Part B) window has actual width of 2.5 ft
[ window blueprint]=[scale]*[actual window]-----> (3/5)*2.5----> 1.5 in
the width of the window in the blueprint is 1.5 in
Part C) Complete the table
For [blueprint length]=4 in
[actual length]=[blueprint length]/[scale]-------> 4/(3/5)----> 20/3 ft
For [blueprint length]=5 in
[actual length]=[blueprint length]/[scale]-------> 5/(3/5)----> 25/3 ft
For [blueprint length]=6 in
[actual length]=[blueprint length]/[scale]-------> 6/(3/5)----> 30/3=10 ft
For [blueprint length]=7 in
[actual length]=[blueprint length]/[scale]-------> 7/(3/5)----> 35/3 ft
For [actual length]=6 ft
[blueprint length]=[actual length]*[scale]-------> 6*(3/5)----> 18/5 in
For [actual length]=7 ft
[blueprint length]=[actual length]*[scale]-------> 7*(3/5)----> 21/5 in
For [actual length]=8 ft
[blueprint length]=[actual length]*[scale]-------> 8*(3/5)----> 24/5 in
For [actual length]=9 ft
[blueprint length]=[actual length]*[scale]-------> 9*(3/5)----> 27/5 in
