[tex]\\ \rm\hookrightarrow \dfrac{1}{2}BH[/tex]

[tex]\\ \rm\hookrightarrow \dfrac{1}{2}(4)(7)[/tex]

[tex]\\ \rm\hookrightarrow 2(7)[/tex]

[tex]\\ \rm\hookrightarrow 14cm^2[/tex]

Given :

  • Base = 4cm
  • Height = 7cm

To find :

  • Area = ?

Formula used :

  • [tex] \sf \frac{1}{2} \times base \times height[/tex]

Solution :

[tex] \tt \frac{1}{ \cancel2} \times \cancel 4 \times 7[/tex]

[tex] \tt \: 2 \times 7[/tex]

[tex] \tt \: 14 {cm}^{2} [/tex]
