Width = 5.5yd
Length = 12yd
<u>Explanation:</u>
Area of rectangle =
Let width of the rectangle = b ,
So, length = 2b+1
Area of rectangle = (length X width) - eqn 1
Putting the value of length and width in above equation 1,
On solving the equation we get,
b = 5.5yd
So, width (b) = 5.5yd
and length = 2(5.5) + 1
l = 12yd
Hence,
Width = 5.5yd
Length = 12yd

Answer:
14400
Step-by-step explanation:
X - X × 75%=3600
X - X × = 3600
X - = 3600
= 3600
= 3600
X = 3600 × 4
X = 14400
