A 150×70 grid has 178 x×y rectangles. Find the value of x+y.
Details and Assumptions:
- Dimensions are expressed as width×height. Thus an x×y rectangle (that is, a rectangle of width x and height y) is considered to be different from a y×x (width y, height x) rectangle. In this problem, you only consider the x×y rectangles, not the y×x ones.
