Question

Please help me with this one!!

Answer 1

`21 in^(2)`

Explanation:

The square in the middle has a length and width of 3, so multiply. 9.

All of the triangles have a base of 3 and a height of 2. The area equation for triangles is

`A=bh(1)/(2)`

So base*height is 6. Divide that by 2 or multiply by 1/2.

You get 3. There are 4 triangles, so multiply that by 4. 12.

Add 12 and 9 together, and you get:

`21 in^(2)`

I hope this helps!
