Let's see what to do buddy...
_________________________________
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 around a rectangular.
Around of rectangular = Perimeter of it
So we must to find the perimeter of the rectangular.
![\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: p = 2(length + width) \\ \\ p = 2(20 + 40) \\ \\ \: \: \: \: p = 2 * 60 = 120](https://img.qammunity.org/2021/formulas/mathematics/high-school/i0wt5x0a0q4oxe5puungqsrm3iv55ygwm9.png)
So Pearl needs 120 meters of wire.
