This coordinate plane shows the shape of a hang glider. The perimeter of the glider is to be trimmed with a special material. What is the minimum length of material needed?
On x axis we will need 24 feets of material. on y axis we will need 2 times 2 feet which is 4 feet for those sides.
now there are lines that are not paralel to x and y so it is not that simple (but not hard either) to calculate lenghts. we can use formula for distance between 2 dots.
we will use dots: (12,7) and (0,2) from that using pythagoras theorem we can see that distance is: d = √12^2 + 5^2 = 13 Total lenght is:
