Answer:
area = Iw
Explanation:
area = lw
where
l = length
w = width
Therefore,
The area of the shaded region = area of the big rectangle - area of the small rectangle
Therefore,
area of the big rectangle = (x+10)(2x+5) = 2x² + 5x + 20x + 50 = 2x² + 25x + 50
area of the small rectangle = (x+1)(x+1) = x² + x + x + 1 = x² + 2x + 1
area of the shaded region = 2x² + 25x + 50 - ( x² + 2x + 1)
area of the shaded region = 2x² + 25x + 50 - x² - 2x - 1
area of the shaded region = x² - 23x - 49
Leaf stomates are the primary sites of transpiration and consist of two guard cells that form a small pore on the surfaces of leaves. The guard cells control the opening and closing of the stomates in response to various environmental stimuli and can regulate the rate of transpiration to reduce water loss.

The following are true of mole ratio
- They are expressed as ratio of mass to molar mass
- It is measured in moles
<h3>How to calculate the mole ratio</h3>
The formula for calculating the mole ratio is expressed according to the formula shown:
Mole ratio is the ratio of the mass of a substance to the molar mass of the same substance.
To calculate the mole ratio
Mole = Mass(g)/molar mass(g/mol)
Hence the following are true of mole ratio
- They are expressed as ratio of mass to molar mass
- It is measured in moles
