The ratio between the perimeter and the breadth of a rectangle is 5 : 1. If the area of the rectangle is 216 sq. cm, what is the length of the rectangle?
Answer: Option
Explanation:
| 2(l + b) | = | 5 |
| b | 1 |
2l + 2b = 5b
3b = 2l
| b = | 2 | l |
| 3 |
Then, Area = 216 cm2
l x b = 216
| l x |
2 | l | = 216 |
| 3 |
l2 = 324
l = 18 cm.

Simply;
2(l+b)=216.
2(5+2)=2016.
12=216.
Ans = 18.
2(l+b)=216.
2(5+2)=2016.
12=216.
Ans = 18.

2(5x+x)=216,
12x=216,
x=18.
12x=216,
