Question

The perimeter of a rectangle is 24 meters and its breadth and length are in the ratio 3 : 5. What is the length of the rectangle?

• A. $\frac{9}{2}$
• B. $\frac{15}{2}$
• C. $\frac{7}{2}$
• D. $\frac{11}{2}$

Answer 1

The correct option is B $\frac{15}{2}$

Given perimeter of rectoangle = 24 m
Let breadth of rectangle be 3x and length be 5 x.

Now, $2(5x+3x)=24$
$\Rightarrow 8x=12$
$\Rightarrow x=\frac{3}{2}$
$\therefore Length=5\times \frac{3}{2}=\frac{15}{2}m$
