Question

ix) The length of base and area of a triangle are 6 cm. and 12 sq.cm respectively, then height of triangle is-- (a) 4 cm. (b) 6 cm. (c) 36 cm. (d) 8 cm.​

Answer 1

Step-by-step explanation:

Area= 1/2* b*h

12= 1/2*6 * h

12/3= h

h=4 cm

Answer 2

Answer :-

• 4 cm .

Question :-

The length of base and area of a triangle are 6 cm. and 12 sq.cm respectively, then height of triangle is :-

(a) 4 cm.

(b) 6 cm.

(c) 36 cm.

(d) 8 cm.

_______________________________________

Formula :-

$\boxed { \star \rm \: \bf \: Area \: of \: triangle = \dfrac{1}{2} \times base \times height}$

______________________________________

Let :-

• Let height be " H "

Solution :-

Now applying the formula, and solve it

$\rm \: \: Area \: of \: triangle = \dfrac{1}{2} \times base \times height$

$\rm \implies 12= \dfrac{1}{\cancel{2}}\times {\cancel6} \times H$

$\rm \implies12=3H$

$\implies \rm H = \dfrac{12}{3}$

$\star\implies\rm \bf\:H = 4cm.$
