The ratio between the length and perimeter of a rectangular plot is 1 : 3 what is the ratio between the length and breadth of the plot?
1 1 : 2
2 2 : 1
3 3 : 2
4 1 : 3
Explanation:
2 : 1 let length of rectangle be lm, breadth be bm. \(\frac{1}{\text{p}} = \frac{1}{3}\) \(\frac{1}{2}\big({1+\text{b}}\big) = \frac{1}{3}\) \({31}={21} + {2}\text{b}\) \({1} = {2}\text{b}\) \(\therefore \frac{1}{\text{b}}=\frac{2}{1}\) \(\therefore \text { required}\text{ ratio}: {2:1}\)

80 students of the same height, stand with both hands stretched all along the sides of a rectangular garden. each student covering a length of 1.75m. Then the perimeter of the garden is:
1 1400m
2 140m
3 14m
4 1400km
Explanation:
140m Distance covered by 1 student = 1.7 \(\therefore\) Distance covered by 80 students = (1.75 × 80)m = 140m \(\therefore\) Perimeter of the garden = 140m
