Kua tāruatia ki te papatopenga
A=\frac{3}{2}\times 3.14
Whakareatia te \frac{1}{2} ki te 3, ka \frac{3}{2}.
A=\frac{3}{2}\times \frac{157}{50}
Me tahuri ki tau ā-ira 3.14 ki te hautau \frac{314}{100}. Whakahekea te hautanga \frac{314}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
A=\frac{3\times 157}{2\times 50}
Me whakarea te \frac{3}{2} ki te \frac{157}{50} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
A=\frac{471}{100}
Mahia ngā whakarea i roto i te hautanga \frac{3\times 157}{2\times 50}.
