Question

The ratio of two sides of a parallelogram is 3 : 5 and its perimeter is 48 m, then the sides of the parallelogram are

• A. 9 m, 14 m
• B. 5 m, 10 m
• C. 9 m, 15 m
• D. 4 m, 8 m

Answer 1

The correct option is C 9 m, 15 m

Let the two sides of parallelogram be 3x and 5x
Perimeter = 2(length+breadth)
$2(3x+5x)=16x$
$\therefore 48=16x$
$\Rightarrow x=\frac{48}{16}=3$
Hence, the sides of the parallelogram are $3\times 3=9$ m and $5\times 3=15$ m.
