Answer 1

Given :

A rectangle with breadth $15$ $cm$ and area $255$ $cm^{2}$.

To find :

The length of the rectangle.

Step-by-step explanation:

• Let the length and breadth of the rectangle be $l$ and $b$ respectively.
• The area of the rectangle will be

        $Area=lb$

• It is given that the breadth and area is $15$ $cm$ and $255$ $cm^{2}$.
• Substitute the value in the given equation

        $255=l(15)$

• Bring the numbers to the other side of the equation.

        $l=\frac{255}{15}$

• Divide the numbers

        $l=17$

• Therefore, the length of the rectangle is $17$ $cm$.

Final answer :

The length of the rectangle whole breadth is $15$ $cm$ and area is $255$ $cm^{2}$ is $17$ $cm$.
