Rectangular plot

The dimensions of a rectangular plot are (x+1)m and (2x-y)m. If the sum of x and y is 3m and the plot's perimeter is 36m. Find the area of the diagonal of the plot.

Correct answer:

S =  64.6875 m2

Step-by-step explanation:

x+y=3 34=2 (x+1)+2 (2 xy)  x+y=3 6x2y=32  Pivot:Row1Row2 6x2y=32 x+y=3  Row261 Row1Row2 6x2y=32 1.33y=2.33  y=1.333333332.33333333=1.75 x=632+2y=632+2 (1.75)=4.75  x=419=4.75 y=47=1.75  a=x+1=4.75+1=423=5.75 m b=2 xy=2 4.75(1.75)=445=11.25 m  S=a b=5.75 11.25=64.6875 m2
