Question

If the height of trapezium is 7cm and sum of parallel sides is 12cm,area of trapezium is

Answer 1

Area = 1/2 x sum of parallel sides x distance between them = 1/2 x 12 x 7 cm² =

42 cm²

Answer 2

Area of trapezium ABCD = Area of ∆ ABD + Area of ∆ CBD

= 1/2 × a × h + 1/2 × b × h

= 1/2 × h × (a + b)

= 1/2 (sum of parallel sides) × (perpendicular distance between them)
