Question

calculate the area of quadrilateral PQRS when length of diagonal PR=10cm and length of perpendiculars from Q and S on PR be 5 cm and 6 cm respectively using herons formula​

Answer 1

Answer:

simple

Step-by-step explanation:

[PQRS]=[PRQ]+[PRS]

=1/2*(5+6)*5

=27.5

ALITER:-

You can use herons formula

•Use baudhayana theorem in each four triangle to find the dimensions of the quadrilateral.

•Then apply heron's formula in Triangle PRQ and PRS.

You can use either methods but latter is lengthy and prone to silly mistakes.
