Find the area of the triangle .

Step-by-step explanation:

Hello There!

The area of a triangle can be found using this formula

where b = base and h = height

the base of the shown triangle is 18 and the height is 7

knowing this information we plug in the values into the formula...

so we can conclude that the area of the triangle is 63 square units

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
