Answer :
- Perimeter of rectangle is 16.44 cm
Given :
- Area of rectangle is 1.76cm
- Width of rectangle is 8cm
To find :
- Perimeter of rectangle
Solution :
First we need to find the length of rectangle by using the Area of rectangle formula after that we have to find the perimeter of rectangle
- Let the length of rectangle be l
- Breadth of rectangle is 8 cm
Area is 1.76cm²
We know that
- Area of rectangle = l × b
Where,
- l is length of rectangle
- b is breadth of rectangle
Substituting the value :
➟ Area of rectangle = l × b
➟ 1.76 = l × 8
➟ l = 1.76/8
➟ l = 0.22
Hence, Length of rectangle is 0.22 cm
Finding the perimeter of rectangle:
- Length of rectangle is 0.22 cm
- Breadth of rectangle is 8 cm
We know that
- Perimeter of rectangle = 2(l + b)
Where,
- l is length of rectangle
- b is breadth of rectangle
Substituting the value :
➟ Perimeter of rectangle = 2(l + b)
➟ 2(0.22 + 8)
➟ 2(8.22)
➟ 16.44 cm
Hence,Perimeter of rectangle is 16.44 cm
Verification :
➟ Area of rectangle = l × b
➟ 1.76 = 0.22 × 8
➟ 1.76 = 1.76
Hence Verified
