The area of the actual castle would be 388,800 sq. ft.
We would multiply each of the sides of the scale model both by 180 to find the side lengths of the actual castle.
So...
180 x 4 = 720
180 x 3 = 540
If Area is equal to Length Times Width, all thats left to do is to multiply the two sides together.
720 x 540 = 388,800
Hope this helped! :D

15 minutes is 1/4 of an hour
How many 15 minutes are in 2 hours?
There are 8 so:
45 x 8 = 360
360 pages
B = amount invested in B bonds
c = amount invested in CDs
so.. she's got $70000 burning a hole in her pocket and she wants to invest them to get a yield of 5000 in interest from both of them.
we know that, whatever "c" and "b" are, we know that
b + c = 70,000.
how much is 13% of b? well, (13/100) * b, or 0.13b
how much is 5% of c? well, (5/100) * a, or 0.05c
we know that, the yield or interest earned from them, must be 5000, thus
0.13b + 0.05c = 5000.

how much did she invest in CDs? well, c = 70000 - b.
