Question

find the area of triangle whose base 14 cm and height 7.8 cm​

Answer 1

Given :

⬤ Base of Triangle is 14 cm .

⬤ Height ot Triangle is 7.8 cm .

To Find :

⬤ Area of Triangle .

Formula Used :

$\bf[\:{Area \: of \: Triangle = \dfrac{1}{2} \times{b} \times{h}\:]}$

• b = base
• h = height

Figure :-

$\setlength{\unitlength}{1.5 cm}\begin{picture}(0,0)\thicklines\qbezier(1, 0)(1,0)(3,3)\qbezier(5,0)(5,0)(3,3)\qbezier(5,0)(1,0)(1,0)\qbezier(3,3)(3,3)(3,0)\put(2.85,3.2){ \bf A }\put(0.5,-0.3){ \bf C }\put(5.2,-0.3){ \bf B }\put(2.7,-0.3){ \bf 14 cm}\put(3.1,1.3){\bf 7.8 cm}\end{picture}$

Solution :

1/2 × b × h

1/2 × 14 × 7.8

1/2 × 14 × 78/10

546/10

54.6

Therefore , Area of Triangle is 54.6 cm².
