Answer 2

Given:

• Length of rectangle=12cm
• Breadth of rectangle=4cm

To find:

• Area of rectangle

Solution:

As we know that formula to find area of rectangle is

$\tt : \implies \: \: Length×breadth$

$\tt: \implies \: \: 12cm×4cm$

$\tt: \implies \: \: 48cm {}^{2}$

So perimeter of rectangle=48cm²

More formulae to know!

• Perimeter of rectangle=2(L+B)
• Area of square=Side²
• Perimeter of square=4×Side
• Area of triangle=½×Base×Height
• Perimeter of triangle=Sum of all sides
