Answer :
The pieces of fabric are already the correct length, so it is just a matter of how many panels will fit into one piece of fabric. 2/(1/2) = 4, so she can make 4 panels from 1 piece of fabric.
Each panel is 4 ft long and 1/2 ft wide
The piece of fabric is 4 ft long and 2 ft wide
So she can therefore fit 4 panels into this. We can calculate this by area
4*1/2=2ft^2
4x2=8ft^2
So 4*2 =8
