In the given figure ABCD is a trapezium in which AB = 40 m. BC = 15 m, CD = 28 m, AD = 9 m and CE ⊥ AB. Area of trap. ABCD is
Given:
AB = 40 m
BC = 15 m
AD = 9 m
CD = 28 m.
In trapezium ABCD,
Area of trapezium = 1/2 × sum of parallel sides × distance between them
= 1/2 × (28 + 40) × 9
= 1/2 × 68 × 9
= 306 m2
