Area of trapezium with parallel sides a and b and the distance between two parallel sides as h |
|
Answer» ONG>Answer: The length of the parallel SIDES of a trapezium are in the rat: 3:2 and the distance between them is 10 cm. If the area of trapezium is 325 cm?, find the length of the parallel sides. Solution: Let the common RATIO be x, Then the two parallel sides are 3x, 2x Distance between them = 10 cm Area of trapezium = 325 cm? Area of trapezium = 1/2 (p, + P2) h 325 = 1/2 (3x + 2x) 10 325 = 5x x 5 - 325 = 25x » X= 325/25 Therefore, 3x = 3 x 13 = 39 and 2x = 2 x 13 = 26 |
