    Answer:

    1. distance = sqrt( (7-7)^2+(2- -8)^2) = 10

    2.  check out desk (0,0 ) => distance = sqrt( (0- -9)^2+(0-0)^2) = 9

    3. last corner ( -3, 4)

    4. area = sqrt( (-10- -10)^2+(10-4)^2) x sqrt( (-3- -10)^2+(10-10)^2) = 6×7 =42

    5. check desk (0,0), south direction = negative y axis => P_beginning (0,-20), P_end (0,-(20+25)) = (0,-45)

    6. A(-2,-1) and B(4,-1) lie in y =-1. AB = sqrt( (-2- 4)^2+(-1- -1)^2) =6

    => area = 3.6×6 =21.6

    => peri = 2x(3.6+6) = 19.2

    7. A(-5,4) and B(2,4), AB =  sqrt( (-5- 2)^2+(4- -4)^2) = 7 => AB is base

    => p = peri = 7+ 8.3×2 = 23.6

    => area = sqrt[px(p-7)x(p-8.3)x(p-8.3)]

                 =sqrt[23.6x(23.6-7)x(23.6-8.3)x(23.6-8.3)] = 302.8
