Explanation:</h2>
As I understand, you need to know the relationship between the area of similar figures. Two shapes are similar if we can turn one into the other by moving, rotating, flipping, or scaling, so this means we can make one shape bigger or smaller.
From math, if we call 
the scaling factor, then the area of one figure (
) divided by the area of another similar figure (
) will be equal to the scaling factor squared. In other words:
In math "of" means times, so...
2/3 of 800 =
2/3 × 800 =
1600/3 = 533 1/3
Answer:
24 x y
Step-by-step explanation:
Simplify the following:
3×4×2 x y
Hint: | Multiply 3 and 4 together.
3×4 = 12:
12×2 x y
Hint: | Multiply 12 and 2 together.
12×2 = 24:
Answer: 24 x y
79.57 times 12% = 70.02
70.02 times 7.75% = 5.43
70.02 plus 5.43 = 75.43
Answer:
m∠ACD = 24°
Step-by-step explanation:
Measure of the interior angles of a polygon = 
Therefore, measure of the interior angles of a rectangle = 
= 
= 90°
m∠BCD = 90°
Since, m∠BCD = m∠BCA + m∠ACD
90° = 66° + m∠ACD
m∠ACD = 90° - 66°
= 24°
Therefore, measure of angles ACD is 24°.
