The answer is ... 16 I think
Answer:
Explanation:
A rectangle is a two-dimensional quadrilateral.
The area is given as:
Area of a rectangle = length x width
Perimeter = 2(L+ W)
where L is the length and W is the width
Condition:
If L and W are increased by 3 feet each;
New length = L + 3
New width = W + 3
Area of new rectangle;
Area = (L + 3) x (W + 3)
= LW + 3L + 3W + 9
Perimeter of new rectangle;
Perimeter = 2(L+3 + W + 3)
= 2(L+W +6)
A gravel covered plain is called a Reg. A reg is a desert basin where the sand has been blown away leaving a gravel covered plain.
Answer:
Nanotechnology helps to improve viscous fingering and the nano-particles can transmit through nanopores of sandstone which helps to increase the recovery by decreasing the surface tension between oil and water. The pore spaces are very fine so water molecules cannot penetrate through all of them in order to push the oil. This is why the nano-particles such as iron (Fe) and Silicon (Si) are used with distilled water. These particles can easily move through the interconnected pores and thereby pushes the oil to move out of it. It is a widely accepted concept in Enhanced Oil Recovery (EOR).
The answer is simple Neptune because it is the only blue planet.
