Points J and K, plotted on the coordinate grid, are two vertices of rectangle JKLM.

Question

Rectangle JKLM has an area of 7 square units.
Point J is located at (2, 1) and point K is located at (-5, 1).
Each vertex of the rectangle is located at a point that has integer coordinates.

Answer 1

clearly the width is 7, since JK is a horizontal line.

so the height is 1.
