Answer 2

Answer:

• Area of the rectangular garden is 420 m².

Step-by-step explanation:

Given that:

• Length of the rectangular garden is 20 m.
• Breadth of the rectangular garden is 21 m.

To Find:

• Area of the rectangular garden.

Formulas Used:

• Area of rectangle = (L × B) sq. units

Where,

• L = Length of the rectangle
• B = Breadth of the rectangle

Substituting the values,

Area of the rectangular garden:

$\sf\hookrightarrow(20\times21)\; cm^2$

Multiplying 20 and 21,

$\sf\hookrightarrow 420\;cm^2$

Hence, area of the rectangular garden is 420 cm².

More Formulas:

• Perimeter of rectangle = 2(Length + Breadth) units
• Area of four walls of a room = {2(Length + Breadth) × Height} sq. units
• Diagonal of a room = $\sf\sqrt{L^2+B^2+H^2}$ units
• Perimeter of square = (4 × Side) units
• Area of square = (Side²) sq. units
