Answer:
\(189\ ft^{2}\)
Step-by-step explanation:
we know that
The area of a kitchen is equal to the area of rectangle minus the area of trapezoid
so
Step 1
Find the area of rectangle
\(b=16\ ft\)
\(h=12\ ft\)
\(A=bh=16*12=192\ ft^{2}\)
Step 2
Find the area of trapezoid
\(A=(1/2)(b1+b2)h\)
\(b1=(16-12)=4\ ft\)
\(b2=2\ ft\)
\(h=(12-11)=1\ ft\)
substitute
\(A=(1/2)(b1+b2)h=(1/2)*(4+2)*1=3\ ft^{2}\)
Step 3
Find the area of a kitchen
\(192\ ft^{2}-3\ ft^{2}=189\ ft^{2}\)
