Answer:
The length is 24.
Step-by-step explanation:
The equation for the perimeter of a rectangle is 2l+2w
Therefore, we have the equation
P=2l+2w
Next, we plug the values we know into the equation.
124=2l+2(38)
Next, we can simplify that
124=2l+76
Subtract 76 from both sides
48=2l
Divide both sides by 2.
l=24
