dth.
Is the correct answer
W= 9 in and L= 12in ???
1 answer:
Answer:
Width = 9 inches , length = 12 inches.
Step-by-step explanation:
Let the width = x inches, then its length x+3 inches.
Perimeter = 2x + 2(x + 3) inches so
2x + 2(x + 3) = 42
4x + 6 = 42
4x = 36
x = 36/4 = 9
So the width is 9 in and length = 9 + 3 = 12 inches.
You are correct.
