    {\huge{\bf{\purple{\mathbb{\underline {Question:-}}}}}}

    The width of a rectangle is 2/3 of it`s length if the perimeter of the rectangle is 80 cm. Find length and width.

    {\huge{\bf{\purple{\mathbb{\underline {Answer:-}}}}}}

    24 and 16cm

    {\huge{\bf{\purple{\mathbb{\underline {Explanation}}}}}}

    let the length be a

    so, width =2a/3

    According to question,

    perimeter = 2(L+B)

    80=2(L+B)

    40=L+B

    40=a+2a/3

    40×3= 5a

    a=24

    so the length is 24 cm and width is 16 cm Answer.
