Answer:
875cm^2
Step-by-step explanation:
since opposite sides are equal
3x-y=2x+y
x=2y                                                      
y=x/2                                                                      ....(i)
thus new length=2x+y
=2x+(x/2)                                                              [using (i)]
=(4x+x)/2
l=5x/2                                                                   .....(ii)
now,
perimeter=2(l+b)=120cm
l+b=60cm            
from figure and using (ii)
[5x/2]+2x-3=60
[5x+4x-6]/2=60
9x-6=120
9x=126
x=126/9
x=14                                                                 ..........(iii)
substitute (iii) in (i)
y=14/2
y=7                                                                  ...........(iv)
From figure,
length=2x+y                                                   [using (iii) and (iv)]
=2x14+7
length=35cm
breadth=2x-3
=2x14-3                                                          ....[using(iii)]
=28-3
breadth=25cm
now,
Area=lxb
=35x25
=875cm^2

The correct question is 
<span>Teresa graphs the following 3 equations: y=2x, y=x2+2, and y=2x2. She says that the graph of y=2x will eventually surpass both of the other graphs. Is Teresa correct? Why or why not?
we have that
y=2x
y=x</span>²+2
y=2x²
using a graph tool
see the attached figure
<span>We can affirm the following
</span>the three graphs present the same domain-----> the interval (-∞,∞)
The range of the graph y=2x  is the interval (-∞,∞)
The range of the graphs y=x²+2 and y=2x² is the interval [0,∞)
therefore
<span>Teresa is not correct because the graph of y = 2x will not surpass the other two graphs since in the interval of [0, infinite) the three graphs present the same range</span>
