Let length be l and breadth be b.
l = 4b. (I)
Perimeter: 12.5 km
Perimeter, P = 2(l+b)
P = 2( 4b +b) = 12.5
4b + b = 12.5/2
5b = 6.25
Therefore, b = 6.25/5
= 1.25 km
Now, from 1,
l = 4*1.25
= 5 km
Area = l*b
= 5*1.25
= 6.25 km^2
Answer: =-x-1.6
Step-by-step explanation: Using the formula, write in standard form.
Hope this helps you out.
So basically you just want to isolate the variable. So you want n on a side all by itself. so first you multiply by -2 to both sides, that will leave you with the equation n+4=18, then you subtract 4 from both sides, this will give you the equation n=14. To make sure this solution is correct, you can plug it back into the equation filling 14 in for n, this equation is 14+4/-2=-9, and this solution works. Hope this helped :)
