# The length of a rectangle is twice the breadth. If area of the rectangle be 417.605 sq.m., then length is :

- 29.08m
- 9.08 m
- 28.90 m
- 28.09 m

**Answer: (3) 28.90 m **

**Explanation:-**

Let the breadth of the rectangular be X m.

The length of a rectangle is twice the breadth.

Then, length of the rectangle = 2 X m

If area of the rectangle be 417.605 sq.m.

Then, X x 2 X = 417.605

2 X^2 = 417.605

X^2 = 417.605/2

X^2 = 288.8025

Square root on both side,

X = 14.45

Then, length of the rectangle is 2 X = 2 x 14.45

= 28.90 m

Hence, the correct answer is option (3) 28.90 m .
