Answer:
Here is your answer buddy!!
Step-by-step explanation:
Length of parallel sides=15 cm and 40 cm
To find height...
by Pythagoras theorem..
c^2= a^2 + b^2
41^2= a^2 + 40^2
1681-1600= a^2
81=a^2
a=9
so, the height of the trapezium is 9cm.
Area of trapezium= 1/2 *h*(a+b)
=1/2*9*(15+40)
=4.5*55
=247.5cm^2
plzzzz mark it as brainliest.
