Question

the perimeter of a paralleogram is 24 cm and one of it's side is 8 cm. find the other sides​

Answer 1

Answer:

other side is = 4cm

Step-by-step explanation:

2xfirst side + 2xsecond side = 24 (SINCE OPPOSITE SIDES OF A PARALLELOGRAM ARE EQUAL

2x8+2x=24

16+2x=24

2x=8

x=4cm

Correct Question:

The perimeter of a parallelogram is 24 cm and one of it's side is 8 cm. Find the other side.

Given:

Parallelogram with

• Perimeter = 24 cm
• One side = a = 8 cm

What To Find:

We have to find the other side (b) of the parallelogram.

How To Find:

To find the other side (b), we have to know

• Perimeter of parallelogram = 2(a + b)
• Then, substitute the values and solve.

Solution:

Using the formula,

⇒ Perimeter = 2(a + b)

Substitute the values,

⇒ 24 cm = 2(8 cm + b)

Remove the brackets,

⇒ 24 cm = 16 cm + 2b

Take 16 to LHS,

⇒ 24 - 16 = 2b

Subtract 16 from 24,

⇒ 8 cm = 2b

Take 2 to LHS,

⇒ $\sf{ \dfrac{8}{2} = b}$

Divide 8 by 2,

⇒ 4 cm = b

∴ Thus, the other side of the parallelogram is 4 cm.
