Answer 1

what he said

Explanation:

Answer 2

`189\ ft^(2)`

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)`
