Q- The parallel lines of a trapezium are 25 cm and 11cm ,while its non-parallel sides are 15 cm and 13 cm .Find the area of trapezium.
Hi!
Here is the answer to your question.
Let DM = x cm. Draw AM ⊥ CD and BN ⊥CD.
ABMN is a rectangle. Therefore, MN = AB = 11 cm.
CN = 25 cm – 11 cm – x cm = (14 – x) cm.
In ?AMD,
Thus, the area of the trapezium ABCD is 216 cm2.
Cheers!
