Question

3. Find the perimeter of a rectangle from the given length and breadth
d) 4.2 cm and 3 cm​

Answer 1

Given :

★ Length of Rectangle = 4.2 cm

★ Breadth of Rectangle = 3 cm

To Find :

★ Perimeter of Rectangle .

Formula Used :

$\sf[\:\:{Perimeter\:of\:Rectangle=2(l+b)\:\:]}$

Solution :

• Length = 4.2 cm
• Breadth = 3 cm

Now :

2 (l + b)

2 (4.2 + 3)

2 (7.2)

14.4

Therefore , The Perimeter of Rectangle is 14.4 cm $.$

═════════════════════════

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