A entry terrace=(8*4)+(4*4/2)*2=48 ft2
A back porch=6*6=36 ft2
A play room=14*16=224 ft2
Aside deck=3*14=42 ft2
A total=48+36+224+42=350 ft2
The area entry terrace is 48 ft2
The area total is 350 ft2

C) A student wants to write a coefficient matrix representing a linear system with two equations and three unknowns.
It is 2x3 times 3x1 = 2x1 matrix
D) A teacher wants to write an augmented matrix representing a linear system with four equations and four unknowns.
It is 4x4 times 4x1 = 4x1 matrix.
Hence option B is correct.
