Answer» -step EXPLANATION:area=1440Given that,Area of trapezium FIELD = 1440 m 2 Height of field = 24 cmRatio of parallel sides 5 : 3Let the sides be 5x and 3x.We know that,Area of trapezium = 21 (Surn of parallel SIDE) × Height1440 = 21 (5x + 3x) × 24 ⇒ 241440×2 = (5x + 3x)120 = 8x ⇒ = 15Hence, longer side = 5 × 15 = 75 cm |
