Answer 1

`Length = 18`

`Width = 27`

Explanation:

Given

Dimension = 20 by 30

Reduction = 10%

Required

Determine the new dimensions

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

`New = Old (1 - Reduction)`

The new length is calculated as:

`Length = 20(1 - 10\%)`

Convert percentage to decimal

`Length = 20(1 - 0.10)`

`Length = 20 * 0.90`

`Length = 18`

The new width is calculated as:

`Width = 30(1 - 10\%)`

Convert percentage to decimal

`Width = 30(1 - 0.10)`

`Width = 30*0.90`

`Width = 27`
