  • Answer:

    length= 25 cm

    width= 15 cm

    Step-by-step explanation:

    FIrst is to write the given into mathematical expressions

    length= x+10

    width= x

    perimeter= 80 cm

    Next is to solve for the perimeter of the rectangle

    p= 2l+2w

    Substitute the length and width

    p= 2(x+10) + 2(x)

    Simplify

    p= 2x+20 + 2x

    p= 4x+20

    Equate the binomial above to 80 to find the dimensions

    4x+20=80

    Solve for the value of x

    4x=60

    x=15

    Substitute the values of x

    length= (15) + 10= 25 cm

    width= 15 cm

    hi, I hope this helps. palike and pabrainliest po :)))
