Answer this ! this is a lightshot/picture answer and you shall be greeted with

The area of the lower-left trapezoid is
.. A₁ = (1/2)(b₁+b₂)h
.. A₁ = (1/2)(36 ft +18 ft)(12 ft)
.. A₁ = 324 ft²

The area of the upper-right trapezoid is
.. A₂ = (1/2)(b₁+b₂)h
.. A₂ = (1/2)(24 ft +12 ft)(18 ft)
.. A₂ = 324 ft²

The area of the floor plan is
.. A = A₁ + A₂
.. A = 324 ft² + 324 ft²
.. A = 648 ft²

The area of the floor plan is 648 square feet.


Check
It can also be computed as (36 ft)(24 ft) - (18 ft)(12 ft) = 648 ft².
