Question

Answer 1

I think it is an equilateral triangle with all the sides are of equal length

so area of equilateral triangle is root 3/4* (side)^2

root3/4 *16

so area is 4 root 3

Answer 2

hi

one side of a traingle is 4 cm 

we cant find the area of the triangle unless we know atleast 2 sides ofit

but this can be solved if it is  equaliteal triangle

area of  equaliteal triangle = √3/4 a²

= a = 4cm

= $\sqrt{3} a^{2} /4$

=> $\sqrt{3} *16 /4$

=>√3 * 4

=>1.73....... = 1.73

=> 1. 73 *4

=>6.92 cm²
