Question

area of a triangle is 36 sq decimeter find it base is 6 dm corresponding hight​

Answer 1

Area of Triangle = $\bf \frac{1}{2} \times base \times height$

$\bf 36 \: dm {}^{2} = \frac{1}{ \cancel2} \times b \times \cancel6 \: dm \\ \bf36 \: {dm}^{2} = 3b \: dm \\ \bf b = \cancel\frac{36}{3} dm \\ \bf b = 12 \: dm$
