Question

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 trapezium ABCD is

Answer 1

(a) 306 m2

In the given figure, AECD is a rectangle.

Length AE = Length CD = 28 m

Now,

BE = AB - AE = 40 - 28 m

Also,

AD = CE = 9 m

Area of trapezium = 1/2 x sum of parallel sides x Distance between them

In the given figure, if DA is perpendicular to AE, then it can be solved, otherwise it cannot be solved.
