    Area of rectangular pizza = 60 x 40
    = 2400

    Area of 2 round pizzas = 2400

    Area of a Circle = r x r x 3.14

    2 (3.14 x r x r) =2400
    3.14 x r x r =1200
    r x r = 1200/π
    r = √381.972
    r = 19.54

    Diameter = 2(19.54)
    = 39.08

    tan 45= 28/x
    28/ tan 45= x
    x=28

    tan 60= 28/y
    28/tan 60= y
    y=16.16

    28+ 16.16=44.16
