Answer:
Length = 10 & width = 3
Step-by-step explanation:
Perimeter = Length + Length + Width + Width
26 = 2Length + 2 Width
26 = 2 ( Length + Width )
13 = Length + width
13 - Length = Width EQUATION 1
Area = Length X Width
30 = Length X ( 13 - Length )
30 = 13Length - Length ^2
Length ^2 - 13Length + 30 = 0
( Length - 3 )( Length - 10 )
Length = 3 or Length = 10
Therefore Length = 10
From equation 1
13 - Length = Width
13 - 10 = width
width = 3
