In the above diagram, ABCD is a rectangle with AE = EF = FB. What is the ratio of the area of the triangle CEF and that of the rectangle?

Answer & solution

  • 16

  • B

    18

  • C

    19

  • D

    None of these

Solution

∵ AB = 3 × EF

Area of (∆CEF)Area of (□ABCD)=12×EF×CBAB×CB

Area of (∆CEF)Area of (□ABCD)=12×EF×CB3×EF×CB=16
