Question

YOUR TURN

Find the length and width of the actual room, shown in
the scale drawing. Then find the area of the actual room.
Round your answer to the nearest tenth.

Answer 1

`Width: (3in)/(8ft) = (5in)/(x) (cross multiply)`

=
`40` ÷3 ≈ 13.3ft

`Width: \frac {3in}{8ft} = (6.5in)/(x)`

= 17.3

`A=e` ×
`w`

`= 13.3` ×
`17.3` ≈
`230.09` ≈
`230.1`
