Question

find the perimeter and area of a triangle with the given dimensions all sides are 4 cm

Answer 1

Hey MATE!

Perimeter of triangle with all sides equal is given by => 3a

Therefore, perimeter of triangle with side 4cm
= > 3(4) = 12 cm

Area of equilateral triangle is given by :
$\frac{ \sqrt{3} {a}^{2} }{4} \\ \\ = > \frac{ \sqrt{3} \times {4}^{2} }{4} \\ \\ = > 4 \sqrt{3} {cm}^{2}$

Hope it helps

Answer 2

Answer:

$\huge \: answer$

Perimeter of triangle with all sides is given by = 3a

Therefore ,perimeter of triangle with side 4cm

=>3(4)=12cm

Area of equilateral triangle is given by :-

$\frac{ \sqrt{3 {a}^{2} } }{4} \\ \longrightarrow \: \frac{ \sqrt{3 \times {4}^{2} } }{ {}^{4} } \\ \longrightarrow \: 4 \sqrt{3 {cm}^{2} }$
