A.) Either #A=w*l# or #1/6=w*1/2#
B.) #w=1/3# km

Explanation:

Let's start with an equation for the area. Since it is rectangular, we know that the park's area is equal to its length times its width, so:

#A=w*l# where #A# is area, #w# is width, and #l# is length.

We know that the length is 1/2 km, and the area is 1/6 km, so we can substitute those in:

#1/6=w*1/2#

We then solve that equation to get the width, so:

#1/6*color(red)(2)=w*1/2*color(red)(2)#
#2/6=w#
#1/3=w#

So our width is 1/3 km

Hope this helps!
