2) What is the perimeter of following
rectangles?
(i) length = 25 cm and width = 18 cm
(ii) length = 38 cm and width = half of length
Answers
Answer:
2.i)86 cm.
2.i)86 cm.2.ii)57 cm.
Step-by-step explanation:
2.i) Perimeter of a rectangle=2(l+b)
=2(25+18)
=86 cm
2.ii)Perimeter of a rectangle=2(l+b)
=2(38+{38/2})
=57 cm

Answer:
(i)Length = 25cm and width = 18cm
Solution:-
Given that,
length (l) = 25 cm
Length (w) = 18 cm
Perimeter of the rectangle = 2(l + w)units
p = 2(25+18)
p = 2(43)
p = 2× 43
⇒p = 86cm
Therefore, The perimeter of the rectangle is "86cm"
(ii)Length = 38cm and width = half of length
Solution:-
Given that,
Length (l) = 38cm
Width (w) = half of length
then, perimeter of the rectangle = 2(l + w)units
p = 2(38+{38/2})
p = 2(38+19)
p = 2(57)
⇒p = 114cm
Therefore, the perimeter of the rectangle is "114cm"
