Sagot :
Answer:
10
Step-by-step explanation:
If the perimeter is 28 then
4+4+l+l=28
Add 4 with 4 and l with l
8+2l=28
Subtract 8 on both sides:
-8+8+2l=28-8
2l=20
Divide 2 on both sides
l=10
So the length is 10
Hope this helps!
Answer:
l = 10 inches.
Step-by-step explanation:
2x + 2*4 = 28
2x + 8 = 28
2x = 28 - 8 = 20
x = 20/2 = 10.
