Hey !
The value of H is 16
=> H/49 = (4/7)^2 ( taking square to rhs)
=> H/49 = 16/49
Cancelling 49 on both sides ,
H= 16

Answer: Choice A
2(2L + L) = 42
=================================================
Explanation:
The length is L, which is some placeholder for a positive number.
The width is twice as much as this, so it's 2L
The perimeter is found by adding up the four sides (two of which are L, the other two are 2L)
So we have L+L+2L+2L = 2(2L+L) representing the perimeter.
Or we could use this formula
P = 2(L+W)
where L and W are the length and width respectively.
Either way, we end up with 2(2L + L) = 42
