Answer:
Really?
Step-by-step explanation:
Ok....................
Let
x-------------> <span>the length of a rectangle
y-------------> the </span>width of a rectangle
we know that
x+y=130-----------> equation 1
and
x=1.6y--------------> equation 2
<span>I substitute 2 in 1
(1.6y)+y=130-------------> 2.6y=130------------> y=130/2.6------> y=50 ft
x=1.6y--------> x=1.6*50---------> x=80 ft
the answer is
</span>the length is 80 ft
the width is 50ft

Step-by-step explanation:
Gradient is just another similar term for slope l, 
, and it can be calculated by 
where 
and 1
is the 
-coordinates of point 
We let 
be point 
and 
be point 
, we can then write the equation:
.
It also says that the points are with a gradient of so 
. We can then write the equation:
