Answer 2

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
