Answer:
The perimeter is 220 , the area should be 100 ,
Step-by-step explanation:The perimeter of the square is 40 because it’s all sides added together & they are all even - The perimeter of a circle is always 360 and this is half of a circle so that is a perimeter of 180; you add that to 40=220. The area is two sides multiplied together=100 for the square. You find the area of the half circle by doing the area of a circle divided by 2.

Answer:
105°
Step-by-step explanation:
Sum of all sides of a triangle = 180°
x = 180° - (45° + 30°)

= 105°
Therefore x is 105°. Hope you understood :)
Answer:
B
Step-by-step explanation:
You first must find the conversion rate. Since you know a 4 ft tall object produces a 5 foot long shadow, you simply divide 4 by 5. This gives you 0.8. Now that you have your conversion rate, you multiply it by the shadow the tree casts, that being 125, and your answer is B, 100.
