Answer
The total area of the quilt is 437.5 in$^{2}$.
Work Step by Step
First we must find the area of a single parallelogram.
Area of a Parallelogram: Area = $b$$h$
Area = $A$
Therefore:
$A$ = (5 in)(3.5 in)
$A$ = 17.5 in$^{2}$
To find the area of all the parallelograms we must multiply by the number of parallelograms. Therefore:
$A$$_{Total}$ = (25)(17.5 in$^{2}$)
$A$$_{Total}$ = 437.5 in$^{2}$
