Question

The perimeter of parallelogram is 32cm if the longer side measures 9.5 cm what is the measre of shorter side

Answer 1

perimeter of parallelogram =2(l+b)
32 = 2(9.5+b)
16 = 9.5+b
16-9.5 = b
6.5 = b
hence b =6.5cm

measure of shorter side is 6.5cm.

Answer 2

The measure of shorter side of parallelogram is 6.5 cm.

Given:

• The perimeter of parallelogram is 32cm
• The longer side measures 9.5 cm.

To find:

• What is the measure of shorter side ?

Solution:

Formula to be used:

According to property of ||gm, it have equal and parallel opposite sides.

• Perimeter of parallelogram:2(longer side+shorter side)

Step 1:

Let the shorter side of || gm is x.

Longer side = 9.5 cm

So,

$32 = 2(9.5 + x)$

Step 2:

Solve the equation for x.

$9.5 + x = \frac{32}{2}$

or

$x = 16 - 9.5$

or

$\bf x = 6.5$

Thus,

Shorter side of ||gm is 6.5 cm.
