The area of a rectangle is 460 square metres. If the length is 15\% more than the breadth, what is the breadth of the rectangular field?
(a)15 metres
(b)26 metres
(c)34.5 metres
(d)Cannot be determined
(e)None of these
Answer
Explanation
Let breadth = $x$ metres. Then, length = $\left(\frac{115 x}{100}\right)$ metres. $\therefore x \times \frac{115 x}{100}=460 \Leftrightarrow x^{2}=\left(\frac{460 \times 100}{115}\right)=400 \Leftrightarrow x=20$.
