Chapter 8 - Geometry - 8.4 Parallelograms and Trapezoids - 8.4 Exercises: 16

Answer

The correct solution: $A$ = 203 ft$^{2}$

Work Step by Step

Errors in the above solution: 1) When determining the area of a trapezoid the lengths of the parallel sides are summed. 2) When determining the area the units should be squared The correct solution: $A$ = (o.5)(11.6 ft)(22 ft + 13 ft) $A$ = (0.5)(11.6 ft)(35 ft) $A$ = 203 ft$^{2}$
