Answer:

[tex]Length = 18[/tex]

[tex]Width = 27[/tex]

Step-by-step explanation:

Given

Dimension = 20 by 30

Reduction = 10%

Required

Determine the new dimensions

Because it is a reduction, the new dimension is calculated using:

[tex]New = Old (1 - Reduction)[/tex]

The new length is calculated as:

[tex]Length = 20(1 - 10\%)[/tex]

Convert percentage to decimal

[tex]Length = 20(1 - 0.10)[/tex]

[tex]Length = 20 * 0.90[/tex]

[tex]Length = 18[/tex]

The new width is calculated as:

[tex]Width = 30(1 - 10\%)[/tex]

Convert percentage to decimal

[tex]Width = 30(1 - 0.10)[/tex]

[tex]Width = 30*0.90[/tex]

[tex]Width = 27[/tex]
