Jawaban:
- d1=40cm
- d2=55cm
d1×d2/2
[tex] \huge \tt = \frac{40cm \times 55cm}{2} \\ \huge \tt = \frac{ \cancel{2.200} {cm}^{2} }{ \cancel2} \\ \huge \tt = 1.100 {cm}^{2} ..[/tex]
[tex] \tt = \frac{ d_{1} \: \times \: d_{2}}{2} [/tex]
[tex] \tt = \frac{40 \: cm \: \times \: 55 \: cm}{2} [/tex]
[tex] \tt = \frac{2.200 \: {cm}^{2} }{2} [/tex]
= 1.100 cm²
