Question

What is the perimeter of the larger of the two similar parallelograms?

10.5 cm
14 cm
18 cm
21 cm

Answer 1

the answer is 21 cm

The difference between the two shapes is the factor of 1.5cm

Answer 2

Option D. 21 cm

Explanation:

We have to calculate the perimeter of the larger parallelograms similar to smaller one.

Since both the parallelograms are similar to their sides will be in the same ratio.

`(3)/(4.5) =(4)/(x)`

Here, x is the unknown side of the larger parallelogram

By cross multiplication

3x = 4 × 4.5

3x = 18.0

x =
`(18.0)/(3)` = 6.0 cm

Since perimeter of a parallelogram = sum of all sides.

= 4.5 + 4.5 + 6.0 + 6.0

= 9 + 12.0

Perimeter = 21.0 cm

Option D. 21 cm
