Can someone please answer this!! There is an equilateral triangle with an area of 4√3 cm². What is the measure of one of the sides. Show your work for credit.

4cm

I wrote on paper as well to be more specific.

Step-by-step explanation:

The formula that determines the area of a equilateral triangle is (√3/4)*a^2

where a is the side of triangle.

so 4√3=(√3/4)*a^2

(4√3)/(√3/4)=a^2

((4√3)*4)/√3=a^2

16=a^2

a=√16

a=4

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
