Question

$PQRC$ parallelogram,$QM$ is the height form $Q$ to $RC$ and $QN$ is the height from $Q$ to $PS$ . If $RC=12cm$ and $QM=7.6cm$ . Find .
(a) the area of the parallegram $PQRC$
( b ) $QN$ if $PS=8cm$

Answer 1

• Area of the parallelogram PQRS = Base× Height
• $12cm\times$ $7.6cm=91.2c{m}^2$

• Area = Base × Height

$=91.2c{m}^2=8cm\times$ $QN$

$QN=91.2÷8=11.2cm$
