STEP (1)
First we need to find the length.
(( length is two times the width ))
Length = 20 × 2 = 40 m
_________________________________
STEP (2)
Pearl will put wire <em><u>around</u></em><em><u> </u></em><em><u>a</u></em><em><u> </u></em><em><u>rect</u></em><em><u>angular</u></em><em><u>.</u></em>
<em>Around</em><em> </em><em>of</em><em> </em><em>rectangular</em> = <em>Perimeter</em><em> </em><em>of</em><em> </em><em>it</em>
So we must to find the perimeter of the rectangular.
So Pearl needs <em>120 meters</em> of wire.
