Question

the ratio of two sides of a parallelogram is 4:3. if its perimeter is 56 cm find the length of its side.

Answer 1

Let the lengths of two sides of the parallelogram be 4x cm and 3x cm respectively
⇒ its perimeter = 2(4x + 3x) cm = 8x + 6x = 14x cm.
$\Rightarrow 56=14x$
$\therefore x=4$
∴ one side = (4 × 4) cm = 16 cm and other side = (3 × 4) cm = 12 cm.
