Question

On a school map, the points (-2, 3), (4, 3), (4, 9), and (-2, 9) represent the four corners of a sand park.

What are the coordinates of the center of the sand park?

Answer 1

if we plot and join the co-ordinates it forms a rectangle.
so co-ordinates of centre means mid-point of diagonal
= (-2+4)/2 ,(3+9)/2
=(1, 6)
