Answer:
x = 3
Step-by-step explanation:
x + x + x + 2 + x + 2 = 16 (combine like terms)
4x + 4 = 16 (subtract 4 from each side)
4x = 12 (divide each side by 4)
x = 3
Let's check:
(3 + 2) × 2 = 10
3 × 2 = 6
10 + 6 = 16
It works.
Answer:
length= 5 km
Width=3 km
Step-by-step explanation:
Length=Width+2
L=W+2
Perimeter = 16 km
Perimeter of the rectangular field = 2(Length+Width)
[tex]16 = 2*(Width+2+Width)\\\16=2(W+2+W)\\\\16=2(2W+2)\\\\16/2=2W+2\\\\8=2W+2\\\\2W=8-2\\\\2W=6\\\\W=6/2\\\\W=3 km[/tex]
Length(L)=Width+2= 3+2=5 km
length= 5 km
Width=3 km
