Answer:

736 Maybe

Step-by-step explanation:

Well what you gotta do is the triangles on the sides can be moved to form mini rectangles. When you do this you get 8 by 15 rectangles and since you have 4 of then you multiply those by 4. 8*15= 120 and 120*4 = 480. Then all you need to fing is the center square pretty easy to find that square right. Its just 16*16 = 256. And 480+256=736.

I hope this helps.

The answer is 736 squared centimeters.

Step by step:

Sides-

16x15=240

240/2=120

120x4=480

Base-

16x16=256

Add them-

256+480=736

Salutations!

<span>There are 318 fiction books in the class library. The number of non fiction book is 47 less than double the number of fictions book. About how many non fiction books are there in the class library?

Let the number of non fiction books me 'NF'.

Let 'F' be fiction

Double means '2', therefore:

2F - 47 = non fiction (NF)

2(318) - 47 = non fiction

As you can see brackets indicate multiplication, therefore you will be multiplying 318 and 2

636 - 47 = non fiction (NF)

Subtract 47 from 636

589 = nonfiction (NF)

There are 589 non fiction books in the library.

Hope I helped (:

Have a great day!</span>
