Question

PQ and SR are parallel sides of a trapezium PQRS and angle PSR = 90°. give that PQ=15cm, SR = 40 cm, and the diagonal PR = 41 cm. calculate the area of the trapezium.​

Answer 1

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
