Hey there!
Parallel sides [AB & DC] = 13 cm and 25 cm
Non parallel [ BC & AD] = 10 cm [equal]
We know,
Area = 1/2 (a+b) * h
Now, We need to find height.
We know,
Pythagoras Theorem,
CF = [√CE² - EF²]
= √(10² - 6²)
= √64
= √(8 × 8)
= 8 cm.
Now area = 1/2 (a+b)*h
= 1/2 × (25 + 13) × 8 cm²
= 152 cm²
Hence , Area = 152 cm²
Hope It Helps YOu!

he has done that only
thanks
oh
i was not understanding
ok
thanks
it is correct. but we can also solve it by herons formula by drawing a parralel line to any non parallel line. By this a parallelogram is formed inside the trapezium
ya
thanks 4 ur answer.
