Question

If the ratio of sides of a rectangle is 2 : 7 and perimeter is 360 m, then find out its length and breadth.

• A. 140m, 40m
• B. 144m, 36m
• C. 160m, 20m
• D. 135m, 45m

Answer 1

The Correct Option is A

Step 1: Let sides be \(2x\) and \(7x\); perimeter gives \(2(2x+7x)=360\).
Step 2: \(18x=360\), so \(x=20\).
Step 3: Length \(=7x=140\) m, breadth \(=2x=40\) m.
\[ \boxed{140\text{ m},\ 40\text{ m}} \]
