Answer :
Answer:length = 9 width = 3
Step-by-step explanation:
length =3x
width = x
perimeter = 24 = 3x + x +3x + x = 8x
8x = 24 therefore x = 3
so length = 3(3) = 9 width = 3
so perimeter = 3+9+3+9 = 24
Answer:length = 9 width = 3
Step-by-step explanation:
length =3x
width = x
perimeter = 24 = 3x + x +3x + x = 8x
8x = 24 therefore x = 3
so length = 3(3) = 9 width = 3
so perimeter = 3+9+3+9 = 24
