The sum of length and breadth of a rectangle is 68 m and the ratio of length and breadth is 11:23. What is the area of the rectangle (in m2 )?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e 1012.
Let length = 11x and breadth = 23x
Sum = length + breadth = 11x + 23x = 34x
Given: 34x = 68
So, x = 68 ÷ 34 = 2
Length = 11x = 11 × 2 = 22 m
Breadth = 23x = 23 × 2 = 46 m
Area = length × breadth = 22 × 46 = 1012 meters2
