If you need to find the area of a rectangle on the coordinate plane, all you need is the length and width of that rectangle! The task is simple - first, determine lengths of edges, then use the Heron formula to find the triangle area. Create a rectangle that has perimeter of approximately 80 and an area less than 60. You can also use the lengths to calculate the area of the rectangle. This can cause calculatioons to be slightly off. See Rectangle definition (coordinate geometry) to see how the width and height are calculated. A = lw A =(10 units)(11 units) A = 110 units 2 The other option, although quite tedious, would be to count all the squares inside the rectangle. A = area For Heron formula, see Calculator of area of a triangle … For a rectangle, the area is equal to the length times the width.
