Length of a rectangle is 12 cm. less than twice its breadth, if the perimeter of rectangle is 192 cm. Find the length and the breadth are ? A. 60 cm. 36 cm. B. 55 cm. 41 cm. C. 63 cm. 33 cm. D. 50 cm. 46 cm.
Answers
Answer
Explanation
Given
The perimeter of the rectangular =60 cm
Length of rectangular is twice of its breadth
Let us consider the breadth of the field =x
Hence, length of the field =2x
Perimetre =2(length+breadth)
Perimeter =2(12x+x)
192=12×13x
192=12×13x
192=156x
x= 192/156
We get,
x=1.23 cm
So, the breadth of the rectangle = 1.23 cm
Then the length of the rectangle =2x
2×1.23
=2×1.23
=2.46 cm
Therefore, the length of the rectangular is 2.46cm
