The area of a rectangle is 96 cm2. If the breadth of the rectangle is ...
Area of rectangle = L×B
96 = L×8
L = 96/8
Length of rectangle = 12cm
Perimeter of rectangle = 2×(l+b)
= 2× (12+8)
= 2×20
Perimeter of rectangle =40 cm
96 = L×8
L = 96/8
Length of rectangle = 12cm
Perimeter of rectangle = 2×(l+b)
= 2× (12+8)
= 2×20
Perimeter of rectangle =40 cm

The area of a rectangle is 96 cm2. If the breadth of the rectangle is ...
Area = 96 cm²
Breadth= 8 cm
L= ?
Perimeter= ?
Area of a rectangle= L× B
L × 8 = 96
L = 96/8=12cm
Perimeter of a rectangle= 2(l+b)
2(12+8)=2×20=40cm
Breadth= 8 cm
L= ?
Perimeter= ?
Area of a rectangle= L× B
L × 8 = 96
L = 96/8=12cm
Perimeter of a rectangle= 2(l+b)
2(12+8)=2×20=40cm

The area of a rectangle is 96 cm2. If the breadth of the rectangle is ...
Given information:
- Area of rectangle = 96 cm^2
- Breadth of rectangle = 8 cm
To find the perimeter of the rectangle, we need to know either the length or the height of the rectangle. However, the given information does not provide the length or the height directly.
Let's assume the length of the rectangle as 'L'.
The formula to calculate the area of a rectangle is:
Area = Length * Breadth
Substituting the given values into the formula:
96 cm^2 = L * 8 cm
To find the value of 'L', we can rearrange the equation:
L = 96 cm^2 / 8 cm
L = 12 cm
Now that we know the length of the rectangle is 12 cm, we can calculate its perimeter.
The formula to find the perimeter of a rectangle is:
Perimeter = 2 * (Length + Breadth)
Substituting the values into the formula:
Perimeter = 2 * (12 cm + 8 cm)
Perimeter = 2 * 20 cm
Perimeter = 40 cm
Therefore, the perimeter of the rectangle is 40 cm, which is option B.
- Area of rectangle = 96 cm^2
- Breadth of rectangle = 8 cm
To find the perimeter of the rectangle, we need to know either the length or the height of the rectangle. However, the given information does not provide the length or the height directly.

The formula to find the perimeter of a rectangle is:
Perimeter = 2 * (Length + Breadth)
Substituting the values into the formula:
Perimeter = 2 * (12 cm + 8 cm)
Perimeter = 2 * 20 cm
Perimeter = 40 cm
Therefore, the perimeter of the rectangle is 40 cm, which is option B.
