Answer
222
Step-by-step explanation:
I hope this is correct but what you do is first divide this shape into three parts. A small rectangle, a bigger one, and then the triangle. With the triangle on the left, you can see that the width is 5 and the length is 9. You multiply those to get 45. With the rectangle in the middle, you can see that the width is 6. So for the length, you take the 8 and add it to the 9 to get 17. So you do 17 x 6 to get 102. And for the triangle, you see that the length is 15. For the width, it would be 5 because the triangle takes one extra cubit off of the rectangle. Finally, you add 45, 102, and 75 to get 222. Hope this helps.
Answer:
D'G' = 52.5 units
Step-by-step explanation:
Since the dilatation is centred at the origin then multiply the original coordinates by the scale factor 3.5
D' = (1 × 3.5, 7 × 3.5 ) = (3.5, 24.5 )
G' = (- 8 × 3.5, - 5 × 3.5 ) = (- 28, - 17.5 )
Calculate D'G' using the distance formula
d =
with (x₁, y₁ ) = D' (3.5, 24.5) and (x₂, y₂ ) = G' (- 28, - 17.5)
D'G' =
=
=
=
= 52.5 units
Simplify to
Both are over 11, so, just sum.
