The area of a trapezium is 30 cm² and the distance between its parallel sides is 4 cm. If one of the parallel sides is of length 0.1 m, find the length of the other parallel side.1). 32). 43). 54). 6 |

Answer» Let the length of the required SIDE be x cm Area of the trapezium = [$(\FRAC{1}{2})$ × (sum of parallel sides) × (Distance between parallel sides)] One of the parallel side = 0.1 m = 10 cm Then, area of the trapezium = {¹/? × (10 + x) × 4} cm² = (20 + 2x) cm² But, the area of the trapezium = 30 cm² (given) ⇒ 20 + 2x = 30 ⇒ 2x = 30 - 20 ⇒ 2x = 10 ⇒ x = 10/2 ⇒ x = 5 ∴ The length of the other side is 5 cm. |
