Agrid map marks the plot of harold’s garden in meters. the coordinates of the quadrilateral-shaped property are g(–8, 3), a(4, 8), r(10, 0), and d(–2, –5). he wants to build a short fence around the garden. the perimeter of his garden is meters.

To calculate for the perimeter of the garden, we have to solve for the measures of each of the sides of the four-sided polygon. That is calculated by getting the distances between consecutive points. 

The equation for the distance is,
         
                            d = sqrt ((x₂ - x₁)² + (y₂ - y₁)²)

Distance from G and A,
                            d = sqrt ((4 - -8)² + (8 - 3)²)
                                 d = 13
Distance from A to R,
                           d = sqrt ((10 - 4)² + (0 - 8)²)
                                  d = 10
Distance from R to D,
                            d = sqrt ((-2 - 10)² + (-5 - 0)²
                                  d = 13
Distance from D to G,
                            d = sqrt ((-8 --2)² + (-5 -3)²)
                                  d = 10

Summing up all the four calculated distances will give us an answer of 46. Thus, the perimeter of the garden is 46 units.
