Question

Question is below (wasn't sure about the answer)

Answer 1

Answer: Choice A)

`H = (SA)/(2(L+W)) - (LW)/(L+W)\\\\`

=================================================

Work Shown:

`SA = 2(LW + LH + HW)\\\\2(LW + LH + HW) = SA\\\\LW + LH + HW = (SA)/(2)\\\\LH + HW = (SA)/(2) - LW\\\\H(L + W) = (SA)/(2) - LW\\\\H = ((SA)/(2) - LW)/((L + W))\\\\H = (SA)/(2(L+W)) - (LW)/(L+W)\\\\`

This is not the only way to solve for H.
