Question

the length and breadth of a rectangle is 17 cm and 16 cm respectely. Find its perimeter and area​

Answer 1

Answer :-

• The perimeter of rectangle = 66cm.
• The area of rectangle = 272cm².

Step-by-step explanation:

To Find :-

• The perimeter of rectangle
• The area of rectangle

Solution:

Given that,

• Length = 17cm
• Breadth = 16cm

Therefore,

• The perimeter :

As we know that,

Perimeter of rectangle = 2(l+b),

Where,

• l = Length
• b = Breadth

=> 2(l+b)

=> [ 2(17+16) ]cm

=> [ 2(33) ]cm

=> 66cm

Hence, The perimeter of rectangle is 66cm.

Now,

• The area :

As we know that,

Area of rectangle = lb,

Where,

• l = Length
• b = Breadth

=> l × b

=> ( 17cm × 16cm )

=> ( 17 × 16 ) cm²

=> 272cm².

Hence, The area of rectangle is 272cm².

Answer 2

Given :-

• Length of the Rectangle = 17cm
• Breadth of the Rectangle = 16cm

To Find :-

• Area of the Rectangle
• Perimeter of the Rectangle

Solution :-

❏ As we know that, Area of Rectangle is given by L × B and Perimeter of Rectangle is given by 2 ( L + B ) where L and B stands for Length and Breadth respectively.

Putting the Values :

➞ Area of Rectangle = L × B

➞ Area of Rectangle = 17 × 16

➞ Area of Rectangle = 272cm²

________________

➞ Perimeter of Rectangle = 2 ( l + b )

➞ Perimeter of Rectangle = 2 ( 17 + 16 )

➞ Perimeter of Rectangle = 2 × 33

➞ Perimeter of Rectangle = 66cm

________________

Therefore :

• Area of Rectangle = 272cm²
• Perimeter of Rectangle = 66cm

★ Additional Info :

Formulas Related to Rectangle :

• Perimeter of Rectangle = 2( l + b)
• Area = Length × Breadth
• Length = Area / Breadth
• Breadth = Area / Length
• Diagonal = √(l)² + (b)²
