Area of a square is ; 10 * 10 = 100
We have 2 squares so total is 200.

Area of a circle is pi* r^2 = 3.14 * 100 = 314
But we have quarter of a circle so area will be 314/4 = 78.5

Total area of the shape is 200 + 78.5 = 278.5

In 2007, the fee to park in a parking garage was $40. In 2005 the fee was 3/4 of the fee in 2007. What was the fee in 2005? $10

Murljashka [212]

Answer:

C. $30

Step-by-step explanation:

So we know that in 2007 the fee was $40 and we want to figure out what is 3/4 of 40.

To solve that we can start off with 40 and divide it by 4. Which is like saying "I'm finding what one fourth of 40 is." The answer to that is 10.

Because 10 is ONE fourth we multiply by 3 to find what 3/4 of 40 is. 10x3=30 and that's why 3/4 of 40 is 30.

Hope that helps and have a great day!
