Question:-

What is the length and area of a rectangle whose perimeter is 24 cm and the breadth is 4 cm?

Given:-

- Breadth of the rectangle = 4 cm

- Perimeter of the rectangle = 24 cm

To find:-



Solution:

❁We know:-
Perimeter of rectangle =2 ( Length + Breadth )

By using this formula we can find length of rectangle

So:-
↣ Perimeter of rectangle =2 ( Length + Breadth )

↣ 24 =2 ( Length + 4 )

↣24 = 2(Length) + 2(4)

↣24 = 2(Length) + 2 × 4

↣24 = 2(Length) + 8

↣24 - 8 = 2(Length)

↣ 16 = 2(Length)

↣2(Length) = 16

↣ Length = 16/2

↣ Length = 8 cm

Now Finally Let's find area :-

❁We know:-
Area of rectangle = Length × Breadth

So:-
⇢Area of rectangle = Length × Breadth

⇢Area of rectangle = 4 × 8

⇢Area of rectangle = 32 cm²
