Question

the area of rectangle is 200 m2. if the length is 20 m find its breadth and perimeter​

Answer 1

Given -

Area = 200m²

Length ( L ) = 20m

To find -

Breadth ( b ) = ? and Perimeter .

Solution-

Area of rectangle = Length × Breath

200 ⠀⠀⠀⠀= 20 x b

b ⠀⠀⠀⠀= 200 / 20

breadth⠀⠀= 10 m

Now Perimeter

as we know Length = 20m and breadth = 10m

Perimeter of rectangle = 2 × ( L + B )

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 2 ( 20 + 10 )

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 2 × 30

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 60 m .

hope it helps you..
