The parallel sides of a trapezium are at a distance of 5 cm and in the ratio of 2:5. If thelength of longer side is 15 cm, find the area of the trapezium. |

Answer» Are(trapezium) = sum of parallel sides ×distance between them /2longer side length = 15means 5x= 15 x=15/5 x=3then other side is 2x= 2×3=6distance = 5so,area= (15+6)(5)/2 =(21×5)/2 =105/2 =52.5cm^2 |
