Question

A game room has a floor that is 75 feet by 20 feet. A scale drawing of the floor on grid paper uses a scale of 4 units:5 feet. What are the dimensions of the scale drawing?

Answer 1

the dimensions of the drawing scale are

60 units by 20 units

Explanation:

Given:

A game room has a floor that is 75 feet by 20 feet

A scale drawing of the floor on grid paper uses a scale of 4 units:5 feet

The length of the drawing scale is

Let actual Length
`l = 75` feet.

actual width
`w = 20` feet.

Drawing
`Length=(l)/(5) * 4 units`

Put the actual length in above equation.

Drawing
`Length=(75)/(5) * 4 units`

Drawing
`Length=15 * 4`

Drawing
`Length=60 units`

The drawing length is 60 units.

For drawing width

Drawing
`width=(20)/(5) * 4 units`

Put the actual width in above equation.

Drawing
`width=(20)/(5) * 4 units`

Drawing
`width=4 * 4`

Drawing
`width=16 units`

The drawing width is 16 units.

Therefore, the dimensions of the drawing scale are

60 units by 16 units
