Answer:
Height of trapezium = √{(17)² - (58-42/2)²}
Height of trapezium = √(289 - 64)
Height of trapezium = √225
Height of trapezium = 15 cm
Two bases = 42 , 58 cm
Area of trapezium = sum of two bases/2 * Height of trapezium
Area of trapezium = 42 + 58/2 * 15
Area of trapezium = 50 * 15
Area of trapezium = 750 cm²
