Question

in the given ABCD is a Trapezium ECB is a triangle and AECD is a parallelogram. area of triangle BCE=210 cm square, EB=6 cm, CD=24 cm. find the area of Trapezium ABCD​

Answer 1

Answer:

180 cm Sq.

Step-by-step explanation:

area of triangle BCE= 1/2×b×h

210=1/2×6×h

210=1/2×6h

210=3h

210÷3= h

70= h

therefore height of triangle is70 cm

area of trapezium = 1/2×sum of its parallel sides × distance between them

=1/2×(6+24+24)×70

=1/2×54×70

= 27×70

Answer = 180 cm Sq.
