Answer:
The length of the rectangle is 25 km
Step-by-step explanation:
Let
x ----> the length of rectangle
y ----> the width of rectangle
we know that
The perimeter of rectangle is
we have
so
simplify
---- > equation A
---> equation B
substitute equation B in equation A and solve for y
Find the value of x
therefore
The length of the rectangle is 25 km
First simplify so. 2x+3=4x-2. then subtract 4x from both sides. so u get -2x+3=-2. then subtract 3 from both sides so -2x=-5. then finally divide both sides by -2 so u get x=5/2
4 thousands equals 40 hundreds.
