The area of this rectangle is 42 units.

What is the area of a polygon?

The area of a polygon refers to the total surface a polygon covers. This can include the total surface of a triangle, rectangle, octagon, etc.

How to calculate the area?

There are specific formulas to calculate the area of different polygons. In the case of rectangles the general formula is:

  • A = length x width

Moreover, because there are diagonal lines, you need to use this formula to calculate the distance of the length and width.

  • √[(x2-x1)²+(y2-y1)²

Length:

(5,2) (12 ,-5) coordinates in the plane for the upper length

  • √(5-12)²+(2- (-5)²
  • √(-7)²+(7)²
  • √49 + 49
  • 9.89

Width:

(2, -1) (5, 2) coordinates in the plane

  • √(2-5)²+(-1- 2)²
  • √(-3)²+(3)²
  • √9 + 9
  • √18
  • 4.24

4.24 x 9.89 = 41.9, which can be rounded as 42 units.
