Hope this helps!
Given:
To find out:
Find the value of t ?
Formula used:
Perimeter = 2 ( length + Breadth )
Solution:
We know that,
Perimeter = 2 ( length + Breadth )
☆ Substituting the values in the above formula,we get
=> 52.2 = 2 ( 5.4 + t )
=> 52.2 = 10.8 + 2t
=> 2t = 52.2 - 10.8
=> 2t = 41.4
=> t = 41.4/2
=> t = 20.7
