Given:

length on scale drawing = 2.5 in or 5/2 in

width on scale drawing = 1.5 in or 3/2 in

The relationship between the actual measurement (in ft) and the scale measurement is given to be:


(1)/(4)\text{ in repr}esents\text{ 4ft}

Hence, the actual length would be:


\begin{gathered} =\text{ }(5)/(2)\text{ in }*\frac{4ft}{(1)/(4)\text{ in}} \\ =\text{ }(5)/(2)\text{ }*16\text{ ft} \\ =\text{ 40 ft} \end{gathered}

The actual width would be:


\begin{gathered} =\text{ }(3)/(2)\text{ in }*\text{ }\frac{4ft}{(1)/(4)\text{ in}} \\ =\text{ }(3)/(2)\text{ }*\text{ 16 ft} \\ =\text{ 24 ft} \end{gathered}

Hence, the actual length and width of the bedroom are 40 ft and 24 ft respectively

Answer:

length = 40 ft

width = 24 ft
