Question

Find the area of the rectangle whose: Length=7.2m Breadth=80cm​

Answer 1

Here length and breadth of the rectangle are given

Length = 7.2m

Breadth = 80 cm

• We will first convert breadth into meters.

80 cm = 80 × 10⁻² m

           =0.8 m

• We have to find out area of rectangle.

To determine the area we will use the formula

area = l × b

Putting the values in the formula

area = 7.2 × 0.8

        =5.76

The area of the rectangle will be 5.76 m²

Answer 2

• As per the given data in the question, we have to find the area of a rectangle having length and breadth is  $7.2m$ and $80cm$ respectively.
• Given data- Length$=7.2m.$

                            Breadth$=80cm.$

        To find- the area of rectangle.

• Step 1- We have to become the same unit of both length and breadth.
• We know that, $1m=100cm.$
• Step 2- So we have to convert $7.2m$ into $cm.$ for converting $m$ into $cm$. we multiply $7.2$ by $100.$ we will get it,

        $=7.2\times100=720cm.$

• As we know the area of the rectangle is,

        Area of rectangle$=length\times breadth.$

• Step 3- We apply the area formula, we will get it,

        $=720\times 80=57600cm^{2}.$
