Question

An equilateral triangle with side 4 has an area of(
a) 12sqrt(3) b) 16sqrt(3) c) 5sqrt(3); cm^ 2 .(d) 4sqrt(3)
Please answer me​

Answer 1

Answer:

$\frac{ \sqrt{3} {a}^{2} }{4}$

this is the formula to find area of equilateral triangle,

where a = length of sides = 4 cm

=> √3 (4)²/4

=> 4√3 cm²

so option (d) 4√3 cm² is correct!

Hope it will help you!

Answer 2

Step-by-step explanation:

Formula for equilateral triangle is

$\frac{ \sqrt{3} }{4} {a}^{2}$

a- side of triangle

value of root 3 is 1.73 (if you want to simplify it further)

just put the values and you will get your answers

good luck !
