#1**0 **

Pythagoreom theorom, assuming that's a right triangle

sqrt(20^2+20^2 = 28.284

1. 28.284

2. 28.284

1/2bh

28.284*(1/2)*16 = 226.274

3. 226.274

226.274+(28.284^2) = 1026.259

4. 1026.259

All assuming that that is a right triangle

Don't answer it yet. Let me review my answer or another person gives input. Been almost 3 years since done this stuff.

Figured it out

112-40=72

72/3=23

1. 23

2. 23

1/2*23*16 = 184

3.184

184+23^2 = 713

4. 713

Each side of the square is 24 in. Long. 112-40=72/3=24

The side length is 24 in.

24*.5(16) = 192in.^{2} is the area of the triangle.

24^2 = 576in.^{2 }is the area of the square.

576+192 = 768in^{2}, so the total area is **768in. ^{2}**.
