Whakaoti i te =1/2bh=192cm^2

$$= \frac { 1 } { 2 } bh = 192 cm ^ { 2 }$$

Whakaoti mō b

$$\left\{\begin{matrix}b=\frac{384cm^{2}}{h}\text{, }&h\neq 0\\b\in \mathrm{R}\text{, }&\left(c=0\text{ or }m=0\right)\text{ and }h=0\end{matrix}\right.$$

Ngā Upane mō te Whakaoti Whārite Rārangi

He hanga arowhānui tō te whārite.

$$\frac{h}{2}b=192cm^{2}$$

Whakawehea ngā taha e rua ki te \frac{1}{2}h.

$$\frac{2\times \frac{h}{2}b}{h}=\frac{2\times 192cm^{2}}{h}$$

Mā te whakawehe ki te \frac{1}{2}h ka wetekia te whakareanga ki te \frac{1}{2}h.

$$b=\frac{2\times 192cm^{2}}{h}$$

Whakawehe 192cm^{2} ki te \frac{1}{2}h.

$$b=\frac{384cm^{2}}{h}$$

Whakaoti mō c

$$\left\{\begin{matrix}c=\frac{bh}{384m^{2}}\text{, }&m\neq 0\\c\in \mathrm{R}\text{, }&\left(b=0\text{ or }h=0\right)\text{ and }m=0\end{matrix}\right.$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$192cm^{2}=\frac{1}{2}bh$$

He hanga arowhānui tō te whārite.

$$192m^{2}c=\frac{bh}{2}$$

Whakawehea ngā taha e rua ki te 192m^{2}.

$$\frac{192m^{2}c}{192m^{2}}=\frac{bh}{2\times 192m^{2}}$$

Mā te whakawehe ki te 192m^{2} ka wetekia te whakareanga ki te 192m^{2}.

$$c=\frac{bh}{2\times 192m^{2}}$$

Whakawehe \frac{bh}{2} ki te 192m^{2}.

$$c=\frac{bh}{384m^{2}}$$
