Chapter 8 - Geometry - 8.4 Parallelograms and Trapezoids - 8.4 Exercises - Page 559: 18


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$^{2}$
