The lenght of rectangle is thrice its breadth . and its perimeter is 48cm. Find its lenght and breadth of rectangle (do it without algebra) .
Answers
Answer:
Length of the rectangle => 3x = 3 × 6 = 18 cm. Hence, the length and breadth of the rectangle are 18 cm and 6 cm respectively.
Step-by-step explanation:
Let the length be 'l' and breadth be 'b'
According to the condition given in the question
l = 3b
The perimeter of rectangle is given 68 cm
To find the length and breadth of the rectangle, we will use the formula of perimeter of rectangle
perimeter of rectangle = 2 ( l + b )
68 = 2 ( 3b + b )
68 = 2 ( 4b )
68 = 8b
b = 68/8
b = 8.5
Therefore, l = 3 × 8.5
l = 25.5 cm
So, the length and breadth of the rectangle will be 25.5 cm and 8.5 cm respectively.
