Question

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. 23 metres
• C. 34.5 metres
• D. Cannot be determined
• E. None of these

Answer 1

The correct option is E

None of these

Let breadth = `x' metres.

Then, length = $\left(\frac{115x}{100}\right)$metres $\therefore$$x\times \frac{115x}{100}=460\iff x^2=\left(\frac{460\times 100}{115}\right)=400\iff x=20$
