[tex]{ \tt{perimeter = 2(l + w)}} \\ { \tt{p = 2(18 + 9)}} \\ { \tt{p = 2 \times 27}} \\ \\ { \underline{ \tt{ \: \: perimeter = 54 \: m \: \: }}}[/tex]
Answer:
54 m
Step-by-step explanation:
First, find the width
162 = 2w × w
162 = 2w²
w² = 162 ÷ 2
w = [tex] \sqrt{81}[/tex]
w = 9 m
┈
Second, find the length
l = w × 2
l = 9 × 2
l = 18 m
┈
Then, find the perimeter
perimeter = 2(l + w)
perimeter = 2(18 + 9)
perimeter = 2(27)
perimeter = 54 m
