Answer
The total area of all seven floors is 13552 m$^{2}$.
Work Step by Step
First we must find the area of a single floor.
Base = $b$ = 88 m
Height = $h$ = 22 m
Area of a Parallelogram: Area = $b$$h$
Area = $A$
Therefore:
$A$ = (88 m)(22 m)
$A$ = 1936 m$^{2}$
To find the area of all the floors we must multiply by the number of floors. Therefore:
$A$$_{Total}$ = (7)(1936 m$^{2}$)
$A$$_{Total}$ = 13552 m$^{2}$
