Solved Examples on Perimeter of Rectangle
Example 1: Find the perimeter of rectangle whose length is 8 cm and breadth is 12 cm.
Solution:
Given, l = 8 and b = 12 cm
So, Substitute both values in perimeter formula,
P = 2(l + b) = 2(12 + 8) = 40 cm
Therefore the perimeter of a rectangle whose length is 8 cm and breadth is 12 cm is 40 cm.
Example 2: Find the perimeter of rectangle whose sides are 2 cm and 4 cm.
Solution:
Given,
l = 2 and another side b = 4 cm.
So, Substitute the both values in perimeter formula,
P = 2(l + b) = 2(2 + 4) = 12 cm
Therefore, the perimeter of a rectangle whose side is 2 cm and another side is 4 cm is 12 cm.
Example 3: Find the perimeter of rectangular carrom board whose sides are 10 cm and 20 cm.
Solution:
Given,
l = 10 and another side b = 20 cm of the carrom board.
So, Substitute the both values in perimeter formula,
P = 2(l + b) = 2(10 + 20) = 60 cm.
Therefore, the perimeter of a rectangular carrom board whose side is 10 cm and another side is 20 cm is 60 cm.
Example 4: Find the perimeter of a bed cot whose sides are 100 cm and 200 cm.
Solution:
Given,
l = 100 and another side b = 200 cm of the bed cot.
So, Substitute the both values in perimeter formula,
P = 2(l + b) = 2(100 + 200) = 600 cm.
Therefore, the perimeter of a bed cot whose sides are 100 cm and 200 cm is 600 cm.
Example 5: Find the perimeter of a compost pit whose longest side is 100 cm and shortest side is 34 cm.
Solution:
Given,
Longest side = 100 cm, so length (l) will be the longest side.
So l = 100 cm.
Shortest side = 34 cm, so breadth (b) will be the shortest side.
So b = 34 cm
So, Substitute the both values in perimeter formula,
P = 2(l + b) = 2(100 + 34) = 268 cm
Therefore, the perimeter of a compost pit whose longest side is 100 cm and shortest side is 34 cm is 268 cm
Perimeter of Rectangle
A rectangle is a two-dimensional plane quadrilateral, with opposite sides equal and all four angles equal. The perimeter of a rectangle can be defined as the sum of the length of all four sides in a rectangle.
In this article, we are going to learn how to find the perimeter of rectangles using formulas, with the help of examples.
