Two sides of a parallelogram are in the ratio 3:4. If its perimeter is 42 cm, find the les
of its sides.​

Answer 1

Step-by-step explanation:

Let the sides be 3x and 4x. Then the perimeter of the parallelogram is 2(3x+4x)=2×7x=14x. The given data implies that 42=14x, so that x=42/14=3. Hence the sides of the parallelogram are 3×3=9 cm and 3×4=12 cm.
