Question

Find the area of an obtuse-angled triangle with a base of 4 cm and a height 7 cm.​

Answer 1

• Base=B=4cm
• Height=H=7cm

Area:-

`\\ \rm\hookrightarrow (1)/(2)BH`

`\\ \rm\hookrightarrow (1)/(2)(4)(7)`

`\\ \rm\hookrightarrow 2(7)`

`\\ \rm\hookrightarrow 14cm^2`

Answer 2

Given :

• Base = 4cm
• Height = 7cm

To find :

• Area = ?

Formula used :

• 
  `\sf (1)/(2) * base * height`

Solution :

`\tt (1)/( \cancel2) * \cancel 4 * 7`

`\tt \: 2 * 7`

`\tt \: 14 {cm}^(2)`
