The width and the length of a rectangular piece of plywood are 4 feet and 8 feet, respectively. Along one edge of the plywood, a strip x inches wide and 8 feet long is removed. Then, along an edge perpendicular to the 8-foot edge, a strip x inches wide is removed. For what value of x will the remaining rectangular piece have width and length in the ratio of 2 to 5? (1 foot = 12 inches)
enter your value"Along one edge of the plywood, a strip x inches wide and 8 feet long is removed. Then, along an edge perpendicular to the 8-foot edge, a strip x inches wide is removed."
this would mean that there are two strips one which is 8(x) and one that is 4(x). The strip shares a square area that is x^2 big. Therefore the area of the strips would be 8(x)+ 4(x)-x^2. I am unsure how you would derive the value of x that would give a ratio of 2:5
