1,800square ft/$1,200
1.5 square ft for $1

Now to find the area of mr. halloran’s office
$18,000/12 months = $1,500 per month
$1,500•1.5 sqft = 2,250 square feet
So mr. Halloran’s office area is 2,250 square feet and he pays $1,500 per month

$(3x^2y)(7x^2y)(-2x^2y)=\\ \\=3\cdot 7\cdot (-2)\cdot x^2\cdot x^2\cdot x^2 \cdot y \cdot y \cdot y=\\ \\= -42\cdot x^{2+2+2}\cdot y^{1+1+1}=\\ \\=-42x^6y^3$
