    Step-by-step explanation:

    Let us suppose that length of Triangle is equal to x.

    that is

    Length = x

    Than

    width = x - 10

    perimeter of Rectangle is

    2 (length) + 2 (width) = 36

    2x + 2 (x-10) = 36

    2x + 2x - 20 = 36

    4x - 20 = 36

    4x = 36 + 20

    4x = 56

    x = 56/4

    x = 14

    so Length of Rectangle is 14 inches

    and

    width = x - 10

    width = 14 - 10

    width = 4
