The parallel sides of a trapezium are 54 cm and 26 cm and the distance between them is 15 cm. The area of the trapezium is

Given


Length of parallel sides is 54cm and 26 cm


Height (h) = 15 cm


We know that area of trapezium is × (sum of parallel sides) × height


Therefore Area of trapezium = × (54 +26) × 15 = 600 cm2.
