1. Step-by-step explanation:

   Question:–

   If the base of the triangle is 8.6cm and height is 4.5cm,what is it’s area ?

   Answer:–

   Given :–

   • The given figure is a triangle.

   • The base of the triangle is 8.6cm.

   • The height of the triangle is 4.5cm.

   To find :–

   Area of the triangle

   Process :–

   As we all know that:-

   [tex]⇒Area \: of \: triangle \: = \frac{1}{2} \times Base \times Height \\ \\ [/tex]

   Inserting the above value in the formula:–

   [tex]⇒Area = \frac{1}{2} × Base × Height \\ \\ ⇒Area = \frac{1}{2} \times 8.6 \times 4.5 \\ \\ ⇒Area = \frac{1}{2} \times \frac{86}{10} \times \frac{45}{10} \\ \\ ⇒Area = 19.35cm²[/tex]

   Therefore,the area of the triangle is 19.35cm².

   ★ More to know

   Some more formulas:–

   [tex]• \: Area \: of \:scalene \: triangle = \frac{1}{2} × Base × Height \\ \\ • \: Perimeter \: of \: scalene \: triangle = a+b+c \\ \\ • \: Area \: of \: equilateral\: triangle = \frac{ \sqrt{3} }{4} × {Side}^{2} \\ \\ • \: Perimeter \: of \: isosceles \: triangle = 2a+b \\ \\ • \: Perimeter \: of \: equilateral \: triangle = 3× Side \\ \\ • \: Area \: of \: isosceles \: triangle = \frac{b {h}^{b} }{2} [/tex]

2. Given :

   • Base of triangle is 8.6 cm.
   • Height is 4.5 cm.

   To find :

   • Area

   Solution :

   [tex] \boxed{\pmb{\tt Area \: of \: triangle = \dfrac{1}{2} \times base \times height}} [/tex]

   [tex] \tt \leadsto \dfrac{1}{2} \times 8.6 \times 4.5 [/tex]

   [tex] \tt \leadsto \dfrac{38.7}{2} [/tex]

   [tex] \tt \leadsto 19.35 [/tex]

   [tex] \bold{\therefore Area \: of \: triangle \: is \: 19.35 cm^{2}} [/tex]
