Explanation Given: Area of trapezoid A = 0.420 m 2 Height = h Lower base b 1 = height h Upper base b 2 = 3 4 b 1 Concept used: The area of a trapezium is equal to the one-half of the product of height and the sum of the bases. A = 1 2 × h ( b 1 + b 2 ) Where, A= area of trapezium, b 1 and b 2 = upper and lower bases of trapezium and h = height of trapezium. Calculation: Let, the height of trapezium is 'h', lower base is b 1 and the upper base is b 2 . Then, according to the given conditions; Height = h ____________ (1) The lower base b 1 = height h _____________ (2) And, the upper base b 2 = 3 4 b 1 or, b 2 = 3 4 h _____________ (3) Now, by putting the above values in the formula of area of trapezium we get; A = 1 2 × h ( b 1 + b 2 ) 0.420 = 1 2 × h ( h + 3 4 h ) 0.420 = 1 2 × h × 7 4 h 0.420 × 8 = 7 h 2 7 h 2 = 3.36 h 2 = 3
