Question

on a scale drawing a building is 5 1/2 in. tall. if the scale of the drawing is 1 in. : 8 ft how tall is the building

Answer 1

Since each inch on the drawing is equal to 8 ft on the real life, then multiply the size of the building in the drawing times 8 to find its actual size:

$\begin{gathered} 5\frac{1}{2}\times8=5\times8+\frac{1}{2}\times8 \\ =40+\frac{8}{2} \\ =40+4 \\ =44 \end{gathered}$

Therefore, the building is 44 feet tall.
