Answer 1

The formula is side squared+(2)(side)(height)=answer
So 10x10=100,
2x10=20,
20x8=160
=100+160
=260.
The answer is 260.

Answer 2

Find the area of the triangles.
1/2(b)(h)
=1/2(10)(8)
=40
Multiply this by 4 (because there are four triangles) to get 160.

The area of the square is 100 (l*w)
 
Add these together to get 260 in^2
