What is the surface area? 17 ft 16 ft 17 ft 19 ft 15 ft

1,317,840

17×17=289×16=4,624×19=87,856×15=1,317,840

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

answer: just subtact the units and then add the non negative : happy to
