Question

1. The length of a rectangle is 6 cm and its perimeter is 16 cm. The area of the rectangle
in square centimetres is
M 06
(2) 60
(3) 48
(4) 12​

Answer 1

Answer:

Step-by-step explanation:

LENGTH=6 cm

PERIMETER=16CM

PERIMETER OF RECTANGLE=2(L+B)

16=2(6+B)

16=12+2B

16-12=2B

4=2B

4/2=B

2=B

BREADTH OFRECTANGLE=2 cm

AREA OF RECTANGLE=LENGTH×BREADTH

=6×2

=12cm²

Answer 2

Given :

• Length of Rectangle = 6cm
• Perimeter of the Rectangle = 16cm

To Find :

• Area of Rectangle

Solution :

Finding the breadth of the rectangle :

We know that,

★ Perimeter = 2(Length + Breadth)

⟶⠀Perimeter = 2(Length + Breadth)

⟶⠀16 = 2(6 + Breadth)

⟶⠀16/2 = 6 + Breadth

⟶⠀8 = 6 + Breadth

⟶⠀8 - 6 = Breadth

⟶⠀2cm = Breadth

And,

We know that,

★ Area = Length × Breadth

⟶⠀Area = Length × Breadth

⟶⠀Area = 6 × 2

⟶⠀Area = 12cm²

So, Area of Rectangle is 12cm²
