ABCD is a trapezium with CD=20 cm and AE=10 cm. Area of square ABFG is half the area of rectangle BFHI. What is the length of BI if area of trapezium ABCD is 190 .
(A) 36 cm (B) 72 cm (C) 18 cm (D) 54 cm (E) None of the above
It is given to us that area of trapezium = 190
It is given to us that area of rectangle is twice the area of square.
Hence, the answer is (A).
