In Fig. 9.27, the perimeter of (ii) is the same as (i). Is the given statement true or false?
Solution:
Given, the perimeter of (ii) is the same as (i).
We have to determine if the given statement is true or false.
Perimeter is the total length of the boundary of any closed shape.
From the figures,
We observe that new sides are added in (ii)
So, perimeter of (ii) will be greater than (i)
Therefore, the given statement is false.
✦ Try This: Find the altitude of a triangle whose area is 54 cm² and base is 12 cm.
Given, the area of triangle is 54 cm²
Base = 12 cm
We have to find the altitude of the triangle.
Area of triangle = 1/2 × base × altitude
54 = 1/2 × 12 × altitude
54 = 6 × altitude
Altitude = 54/6
= 9 cm
Therefore, the altitude of the triangle is 9 cm.
