Make a sketch of the region enclosed by the line \(l\): 2x + 5y = 10 and the positive coordinate axes. Draw a square that fits snugly into the triangular region, with one corner at the origin, the opposite corner on the line, and other two vertices on the axes. Find the side length of the square.

x and y will have the same value for the vertex that is  on the given  line         so x = y at that point

 

sub into the equation of the line

 

2x + 5x = 10

x = 10/7      this is the side length
