Question

the length of a reactangukar plot of land exceeds its breadth by 23m.If length is deacreased by 15m and the breadth is increased by 7m,the area is reduced by 360m square.find the length and breadth of the plot

Answer 1

Let length be x  Thus,breadth=23-x  According to the problem , (X-15)(x-48)=x(x-23)-360 X^2-48x-15x+720=x^2-23x-360 -48x-15x+720=-23x-360 -40x=-1080 X=27  Therefore,length is 27m and  Breadth is x-23=5m
