If the adjacent sides of a rectangle whose perimeter is 60 cm are in the ratio 3 : 2, then what will be the area of the rectangle?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 216 cm2
Formula Used:
Perimeter of rectangle = 2( l + b)
Area of rectangle = l × b
Explanation:
Let the length and breadth of rectangle be 3x and 2x respectively.
According to th egiven question,
2(3x + 2x) = 60
⇒ 10x = 60
⇒ x = 6
So, length = 18 cm and breadth = 12 cm
Now, Area of rectangle = l × b = 18 × 12 = 216 cm2
Hence the required answer is 216 cm2.
