Which rule describes the composition of transformations that maps ABC to A"B"C"

Answer && Step-by-step explanation:

We know that area for rectangle/square is Width * Height

Triangles 1/2 * Base*Height

we can see the height of the triangle will be 6 feet, as 10 feet is the "height" (length) of the rectangle

solve by multiplying the rectangle's sides (I cant see if that is a 9 or not but:)

9*10 = 90

keep it in mind, now we know 9==base for triangle, thus;

(9*6)*1/2==27

90+27

117 sq ft.
