Question

The adjacent sides of a parallelogram are in the ratio of 4:3. if the longer of the two sides is 14 cm, find the perimeter of the parallelogram.

Answer 1

Answer:

Perimeter= 49cm

Step-by-step explanation:

Adjacent sides= 4:3

Let the sides be 4x and 3x respectively.

4x= 14 cm

x= 14/4

=7/2 cm

3x=3*7/2=21/2 cm

Opposite sides of a parallelogram are equal in length.

Perimeter= 2(14+10.5)

=49cm

Answer 2

Answer: 49 cm

Step-by-step explanation:

let the length be 4x and breadth be 3x.    [since ratio given is 4:3]

A/Q

       4x = 14 => x = 14/4 =7/2cm

Now,

        perimeter = 2(l+b) = 2( 3x + 4x )

                                       = 2 * 7x

                                       = 2*7*7/2

                                       = 49 cm

Hence, perimeter is 49 cm.
