    Answer:

    40 in^2

    Step-by-step explanation:

    The initial dimensions of the paper are:

    L=10 in (length)

    W=8 in (width)

    After the paper is cut along the diagonal, we remain with a right triangle, of which the length and the width corresponds to the base and the height.

    For a triangle, the area is calculated as

    A=\frac{1}{2}bh

    where

    b is the base

    h is the height

    Here we have:

    b=L=10 in\\h=W=8 in

    Therefore, the area of the triangle is:

    A=\frac{1}{2}(10)(8)=40 in^2
