Question

The lengths of the two adjacent sides of a paralleogram are 3x and 5x.Its perimeter is 480 cm.Find the value of x.

Answer 1

Answer:

150 cm and 90 cm

x = 30

Step-by-step explanation:

In parallelogram opposite sides are equal in length so if two adjacent sides are 5x and 3x then the sides opposite to these must be of same length.

Sides : 5x, 3x, 5x and 3x.

Here,

Perimeter = 480 cm

= > sum of all sides = 480 cm

= > 5x + 3x + 5x + 3x = 480 cm

= > 16x = 480 cm

= > x = 480/16 cm = 30 cm

Hence two sides are 5x = 5(30cm) = 150 cm and other two are 3x = 3(30cm) = 90 cm
