Question 77
The length of a rectangular plot is thrice its breadth. If the area of the rectangular plot is 867 $$m^2$$,then what is the length of the rectangular plot ?
Solution
Let the breadth of the rectangle be x
So, lenght of the rectangle be 3x
Area of rectangle = $$Length\times Breadth$$
According to the question,
$$3x\times x$$=867 $$m^2$$
$$x^2$$=$$289$$
$$x$$=$$17$$
Required length = 51 m
