Question
The ratio of the length of the parallel sides of a
trapezium is 3:2. The shortest distance between them is 15cm. If the area of the trapezium is 450cm2, the sum of the length of the parallel sides is.Solution
Let the length of the parallel sides is 3x and 2x. Area of the trapezium = ½ (length of parallel sides) ×h 450 = ½(3x+2x) ×15 5x= 60 X = 12 sum of the length of the parallel sides is =3x+2x =5x =60cm
