<h2>Answer:</h2>

\boxed{A=93.5in^2}

<h2>Step-by-step explanation:</h2>

To find the area of an ordinary piece of copier paper I have attached a figure below. As you can see, this ordinary piece of copier paper is a rectangular shape having the following dimensions:

THE FIRST SIDE:

L_{1}=8.5in

THE SECOND SIDE:

L_{1}=11in

The area of a rectangle can be found as:

A=L_{1}\times L_{2}=(8.5)(11)=93.5in^2

The area of the triangle ABC is 207.5 square units.

Explanation:

The measurements of the sides of the triangle are AB=19, AC=24 and m\angle A=65^{\circ}

We need to determine the area of the triangle ABC.

<u>Area of the triangle:</u>

The area of the triangle can be determined using the formula,

{Area}=\frac{1}{2} b c \sin A

where b=19, c=24 and m\angle A=65^{\circ}

Substituting these values in the above formula, we get,

{Area}=\frac{1}{2}(19)(24)  \sin 65^{\circ}

Simplifying the values, we get,

{Area}=\frac{1}{2}(456) (0.91)

{Area}=\frac{1}{2}(414.96)

{Area}=207.48

Rounding off to the nearest tenth, we get,

{Area}=207.5

Thus, the area of the triangle ABC is 207.5 square units.
