Answer:
<u>Given triangle:</u>
- ΔXYZ
- X(-1,2), Y(2,1), Z(-1, -2)
<u>D₀.₅(ΔXYZ) results in:</u>
- (x, y) → (0.5x, 0.5y)
- X'(-0.5, 1), Y'(1, 0.5), Z(-0.5, -1)
Answer:
150 square feet
Step-by-step explanation:
It is half of the yard, because it extends from the corners. To find the area of the triangle of grass, you have to find the product of the legs divided by two.
30*10=300
300/2=150
150 square feet of Mr. West's backyard is covered in grass
The solution to this equation is x=4.6 because 19.32/4.2=4.6
