Correction: 7/15 – Found the point of intersection of the two lines and then calculated the area of the small triangle. Trying to figure out a non-algebraic way of solving this.

Taking the side of the square as 6 units and the axes along the two sides of the square, the intersection is (1.2, 3.6) The shaded region is area of trapezoid minus area of triangle, which is 18 – 1.2 = 16.8 sq units. The fraction is therefore 16.8/36 = 7/15.

260/9? Or 28.8 repeating percent?

13/30
