Question

PQRS is a parallelogram and diagonals PR and SQ bisect at O. If PO$=3.5$cm and OQ$=4.1$ cm. What is the length of the diagonals?

Answer 1

$PQRS$ is a parallelogram where $PR$ and $SQ$ are diagonals.

$PR$ and $SQ$ bisect at $O$

$PO=3.5cm$ and $OQ=4.1cm$

$\Rightarrow$ $PR=2\times PO=2\times 3.5cm=7cm$

$\Rightarrow$ $SQ=2\times OQ=2\times 4.1cm=8.2cm$

$\therefore$ The length of the diagonals are $7cm$ and $8.2cm$
