  1. Step-by-step explanation:

    Area of Rectangle = Length × Breadth

    400 = 40 × Breadth

    Breadth = 10 m

    Perimeter = 2(L + B)

    = 2(40 + 10)

    = 100 m

    Answer:

    Given :-

    Area of Rectangle = 400 m²

    Length = 40 m

    To Find :-

    Breadth

    Perimeter

    Solution :-

    At first we need to find the breadth of rectangle. Then we need to find the perimeter by using the formula.

    [tex] \mid \pmb{Breadth = \dfrac{Area}{Length}} \mid[/tex]

    Breadth = 400/40

    Breadth = 40/4

    Breadth = 10 m

    Finding Perimeter

    [tex] \mid \pmb{Perimeter = 2( \ell + b)} \mid[/tex]

    [tex] \sf \: Perimeter = 2(40 + 10)[/tex]

    [tex] \sf \: Perimeter = (2 \times 40) + (2 \times 10)[/tex]

    [tex] \sf \: Perimeter = 80 + 20[/tex]

    [tex] \sf \: Perimeter = 100 \: m[/tex]
