Let the unequal side be ( x ) m
Each Equal side = ( 2x - 5 ) m
Perimeter = 2( 2x - 5 ) + x
55 = 4x - 10 + x
65 = 5x
13 = x
Length of unequal side =13 m
Length of equal sides = 26 - 5 = 21 m
Each Equal side = ( 2x - 5 ) m
Perimeter = 2( 2x - 5 ) + x
55 = 4x - 10 + x
65 = 5x
13 = x
Length of unequal side =13 m
Length of equal sides = 26 - 5 = 21 m
