Question:-
[tex] \\ [/tex]
What is the length and area of a rectangle whose perimeter is 24 cm and the breadth is 4 cm?
[tex] \\ [/tex]
Given:-
[tex] \\ [/tex]
- Breadth of the rectangle = 4 cm
[tex] \\ [/tex]
- Perimeter of the rectangle = 24 cm
[tex] \\ [/tex]
To find:-
[tex] \\ [/tex]
[tex] \\ [/tex]
[tex] \\ [/tex]
Solution:
[tex] \\ [/tex]
❁We know:-
Perimeter of rectangle =2 ( Length + Breadth )
[tex] \\ [/tex]
By using this formula we can find length of rectangle
[tex] \\ [/tex]
So:-
↣ Perimeter of rectangle =2 ( Length + Breadth )
[tex] \\ [/tex]
↣ 24 =2 ( Length + 4 )
[tex] \\ [/tex]
↣24 = 2(Length) + 2(4)
[tex] \\ [/tex]
↣24 = 2(Length) + 2 × 4
[tex] \\ [/tex]
↣24 = 2(Length) + 8
[tex] \\ [/tex]
↣24 - 8 = 2(Length)
[tex] \\ [/tex]
↣ 16 = 2(Length)
[tex] \\ [/tex]
↣2(Length) = 16
[tex] \\ [/tex]
↣ Length = 16/2
[tex] \\ [/tex]
↣ Length = 8 cm
[tex] \\ [/tex]
Now Finally Let's find area :-
[tex] \\ [/tex]
❁We know:-
Area of rectangle = Length × Breadth
[tex] \\ [/tex]
So:-
⇢Area of rectangle = Length × Breadth
[tex] \\ [/tex]
⇢Area of rectangle = 4 × 8
[tex] \\ [/tex]
⇢Area of rectangle = 32 cm²
