let CF=FE=EB= a units. Area of ABC = 1/2XBASEXHEIGHT = 1/2X 3aX AF square units. but considering ACF as triangle , using area formula 1/2XCFXAF =27.4 squareunits. a X AF=54.8 Square units. so, AF = 54.8/a. Substitute in the area of triangle ABC=1/2X 3a X54.8/a = 82.2 square units.

Paul and Nadia together have 85 more stickers than Jim.
Paul and Nadia have a total of 6u+25
Jim has 1u
So 5u+25 = 85
5u=60
1u=12
