Answer:
Length = 12 m, Width = 8 m
Step-by-step explanation:
Let the width of the rectangle is b.
Length, l = 4+b
The perimeter of the rectangle = 40 m
We know that,
Perimeter of rectangle = 2(l+b)
2(4+b+b) = 40
4+2b = 20
Subtract 2 from boths sides,
2b = 16
b = 8
Width = 8 m
Length = 4+8 = 12 m
Hence, the length and the width of the rectangle is 12 m and 8 m respectively.

Answer:
5.2%
Step-by-step explanation:
((999.4 × 100) ÷ 950) - 100
(99,940 ÷ 950) - 100
105.2 - 100
5.2
The answer is 5+b, so when b= 14.99, then 5+14.99=$19.99
hope this helps!
