Question

Consider a rectangle of length $4cm$ and breadth $3cm$.Find the area of given rectangle with suitable units;
$\begin{array}{rl}& A.12c{m}^2\\ & B.12cm\\ & C.13c{m}^2\\ & D.13cm\end{array}$

Answer 1

Hint: For the above question, first consider a rectangle, its breadth and length after that directly apply the formula of area of rectangle and put all values , then calculate it to get the value of area.

Complete step-by-step answer:
To find the area of a given rectangle, let us consider a rectangle of length $4cm$ and breadth $3cm$. In the below figure we have the required rectangle.
 

We also know that the area of the rectangle is a product of its length and breadth.
 Therefore,
Area of rectangle = length $\times$ breadth
Area of rectangle= $4cm\times 3cm$
Now $cm\times cm=c{m}^2$ and number to number, then we get
Area of rectangle= $12c{m}^2$
It is the required area of the rectangle.

Hence option A is the correct option.

Note: Rectangle is one of the types of quadrilaterals, which have opposite sides equal and parallel. Also all angles are equal to ${90}^{\circ }$. In geometry there are several types of quadrilaterals, each quadrilateral has different properties.
