Answer 1

Given : -

Sides are 3cm and 4cm.

To Find : -

Area of rectangle = ?

Formula : -

Area of Rectangle = l × b

Step-by-step Explanation : -

Length = 3cm

Breadth = 4cm

By Using the above Formula : -

Area of Rectangle = l × b

3 × 4

12cm²

Therefore , the area of rectangle is 12cm² ..

Answer 2

Given:

$</p><p>\bullet\:\:\textsf{Length (l) = \textbf{3 cm}}$

$\bullet\:\:\textsf{Breadth (b) = \textbf{4 cm}}$

$\bigstar \: \underline{\boldsymbol{According\: to \:the\: Question\:now :}}$

$: \implies \: \sf Area = 3 \: \times \: 4$

$: \implies \: \underline{ \boxed{\sf \:Area \: = \: 12 \: {cm}^{2} }}$
