Answer:

Explanation:

The formula for calculate the area of a rectangle is:

A=lw

Where "l" is the length and "w" is the width.

You can identify that the dimensions of the garden box are:

$l=12ft\\w=8ft$

Therefore, its area is:

$A=(12ft)(8ft)\\\\A=96ft^2$

SInce Brianna wants to reduce it by a scale factor of
(1)/(2) , the area of the new garden is:

$Area\ of\ new\ garden=(1)/(2)(96ft^2)\\\\Area\ of\ new\ garden=48ft^2$
