The length of each side of an equilateral triangle is 74mm, correct to the nearest millimeter. calculate the smallest possible perimeter of the triangle.

220.5 mm.

Step-by-step explanation:

The smallest value each side could be is 73.5 mm so the smallest possible perimeter is 3 * 73.5

= 220.5 mm.

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
