For problems \(89-92\), do the arithmetic with a calculator. The volume \(V\) of an atrium in a hotel is \(648,000 \mathrm{ft}^{3}\). The rectangular floor of the atrium is \(90 \mathrm{ft}\) wide and \(120 \mathrm{ft}\) long. Solve the formula \(V=L W H\) for \(H\), and use it to find the height of the atrium.
Each of the three sides of an equilateral triangle is the same length. If \(P\) is the perimeter of the triangle and \(L\) is the length of a side, write a formula in \(P\) and \(L\) for the perimeter of an equilateral triangle and solve this formula for \(L\).
For problems 97-100, the symbol > means "greater than," and the symbol \(<\) means "less than." Replace the blank with < or \(>\) to create a true statement. 15 _____ 2
