In Fig. 9.27, the perimeter of (ii) is 18 units. Is the given statement true or false?
Solution:
Given, the perimeter of (ii) is 18 units.
We have to determine if the given statement is true or false.
Perimeter is the total length of the boundary of any closed shape.
Perimeter = sum of all sides
From the figure (ii),
The sum of all sides = 18 units
Therefore, the perimeter is 18 units. Hence, the given statement is true.
✦ Try This: Find the perimeter of parallelogram if its base is 10 cm and the distance between the opposite sides is 5 cm.
Given, base, b = 10 cm
Distance between the opposite sides = 5 cm
We have to find the perimeter of parallelogram
Perimeter of parallelogram = 2(a + b)
= 2(5 + 10)
= 2(15)
= 30 cm
Therefore, the perimeter of the parallelogram is 30 cm.
