Answer:
I'm pretty sure it's A.
Step-by-step explanation:
the axis of symmetry says x=
so it would have to be and x value
P = 2l + 2w
Subtract both sides by 2w
P - 2w = 2l
Divide both sides by 2
(P - 2w) / 2 = l
In our problem,
w = 7 in
P = 42 in
Let's plug our values into the formula above.
(42 in - 2(7 in) / 2 = l
(42 in - 14 in) / 2 = l
28 / 2 = l
14 in = length
