Tohaina
Kua tāruatia ki te papatopenga
RP=55cm^{2}
He hanga arowhānui tō te whārite.
\frac{RP}{R}=\frac{55cm^{2}}{R}
Whakawehea ngā taha e rua ki te R.
P=\frac{55cm^{2}}{R}
Mā te whakawehe ki te R ka wetekia te whakareanga ki te R.
PR=55cm^{2}
He hanga arowhānui tō te whārite.
\frac{PR}{P}=\frac{55cm^{2}}{P}
Whakawehea ngā taha e rua ki te P.
R=\frac{55cm^{2}}{P}
Mā te whakawehe ki te P ka wetekia te whakareanga ki te P.
