Answer:
Step-by-step explanation:
Formulas:
Area of a rectangle/square:
<u>Big Rectangles (2):</u>
7*3=21
Multiply by 2
21*2= 42 in
<u>Long rectangles (2)</u>
7*1=7
7*2= 14 in
<u>Short rectangles (2):</u>
3*1=3
3*2= 6 in
<u>Total: </u>
Add.
42+14+6= 62 in2
Because the cos theta < 0 then theta must be an obtuse angle
so a^2 + b^2 < a^2
C
m = ±
m² = n ( take square root of both sides )
