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]
