find the breadth and the perimeter of a rectangle whose length is 10m and area is 40m^2
Answers
Given :-
- Length of a rectangle = 10 m
- Area of rectangle = 40 m²
Find :-
- Breadth & Perimeter of rectangle
Formula
Let,
Length be L m
So,
➩ Area of rectangle = 40
➩ Length × Breadth = 40
➩ L × 10 = 40
➩ L = 40/10
➩ L = 4
Since,
Length be 4 meter.
Now
➩ Perimeter of rectangle = 2 × (Length + Breadth)
➩ Perimeter of rectangle = 2 × (4 + 10)
➩ Perimeter of rectangle = 2 × 14
➩ Perimeter of rectangle = 28 m
⠀⠀ Since,
- Perimeter of rectangle will be 28 m

\large\bf{\pink{Solution:-} }Solution:−
Given :-
Length of a rectangle = 10 m
Area of rectangle = 40 m²
Find :-
Breadth & Perimeter of rectangle
Formula
\boxed{\underline{\tt{\red{\:Perimeter_{rectangle}\:=\:2\times (Length+Breadth)}}}}
Perimeter
rectangle
=2×(Length+Breadth)
\boxed{\underline{\tt{\purple{\:Area_{rectangle}\:=\:(Length \times Breadth)}}}}
Area
rectangle
=(Length×Breadth)
Let,
Length be L m
So,
➩ Area of rectangle = 40
➩ Length × Breadth = 40
➩ L × 10 = 40
➩ L = 40/10
➩ L = 4
Since,
Length be 4 meter.
Now
➩ Perimeter of rectangle = 2 × (Length + Breadth)
➩ Perimeter of rectangle = 2 × (4 + 10)
➩ Perimeter of rectangle = 2 × 14
➩ Perimeter of rectangle = 28 m
⠀⠀ Since,
Perimeter of rectangle will be 28 m
