ANSWER 1
Since this is an irregular surface, you will have to use integration techniques: for example, divide the surface into many narrow strips, consider each strip to be a rectangle and calculate its area as such, add all up. The more narrow you make the strips, the more accurate will be your estimate.
ANSWER 2
The best method depends on the accuracy required of your measurements. If you require accurate and precise results, use a scientific instrument that's specially designed to measure the area of leaves. E.g. AM300 Leaf Area Meter
[See related link below for more information]
My AM300 can store the image, and will analyse it to measure all sorts of useful parameters, like perimeter. I need a lightweight instrument which I can carry for hours, and it only weighs 1.8kg . Other models which are called 'portable' weigh 6.8kg!
If you do not require a high degree of accuracy, you can use the method described in ANSWER 1. However, you may find it quicker to draw around the leaf, then cut out and weigh the paper. By comparison to the weight of a known area of the same paper, you can calculate the area of the leaf. However, when using methods which involve cutting paper, you must cut around the perimeter extremely carefully. Similarly, you must be highly accurate when weighing. I am not sure that paper - even heavy paper - is heavy enough to make the relative error <0.5%.
You can opt for a method where you draw around the leaf on graph paper, then estimate how many grid squares are included in the area. However, grid squares that are partly included in the area must be approximated so introduce inaccuracies.
I have used software called imageJ to draw an irregular polygon on a photo of my leaf. I investigated C.hirsuta leaves, which are a similar size toArabidopsis, so it was possible to click a enough points on the image to accurately trace the perimeter, without it taking hours. To trace the perimeter of a larger leaf, you will have to make hundreds of clicks. By my experience, this will take a morning per leaf!

What is the coefficient factor to calculate tomato leaf area?
The coefficient factor to calculate tomato leaf area typically varies based on the method used, but a common approach is to use a coefficient of 0.7 to 0.9 for estimating leaf area from leaf dimensions. For example, if measuring the length and width of the leaf, you might use the formula: Leaf Area = Length × Width × Coefficient Factor. This coefficient accounts for the leaf's shape and size variability among different tomato varieties. Always refer to specific research or guidelines for precise calculations related to your particular study or application.

What is the volume of a leaf?
Which leaf are you talking about? If you mean the formula for the leaf shape formed by 2 overlapping sectors of a circle, it's (((r^2)pi)/2)-(r^2). This is basically adding up the 2 sectors, and subtracting the square that is formed by them (which leaves the leaf shape)

Why calculate leaf surface area with transpiration?
Calculating leaf surface area helps estimate the total surface available for transpiration. Transpiration is the process where water is evaporated from the surface of the leaf into the atmosphere, which is important for plant cooling and nutrient uptake. By knowing the leaf surface area, we can better understand the potential transpiration rate and overall water requirements of the plant.
What is the formula for transpiration?
The formula for transpiration is: Transpiration = (Amount of water transpired) / (Area of leaf surface) * (Time taken)

How do you calculate leaf area duration LAD?
Leaf area duration (LAD) can be calculated by summing the leaf area at each measurement time point throughout the growing season. It is commonly calculated by using the trapezoidal rule to estimate the area under the curve of leaf area over time. This provides an integrated measure of the total leaf area produced by a plant over a specific period.

What is differences in leaf areas using a graph paper and leaf area meter?
The main difference is that using graph paper will give less precise measurements. Also, due to human errors, using graph paper is not reliable; results vary between different attempts to measure the same leaf. This is because grid squares that are partly included in the area must be approximated so introduce inaccuracies. Leaf Area Meters are scientific instrument that are specially designed to measure the area of leaves. E.g. AM300 Leaf Area Meter My AM300 can store the image, and will analyse it to measure all sorts of useful parameters, like perimeter. I need a lightweight instrument which I can carry for hours, and it only weighs 1.8kg . Other models which are called 'portable' weigh 6.8kg!
How is leaf area index of pak choi calculated?
The leaf area index (LAI) of pak choi can be calculated by measuring the total leaf area and dividing it by the ground area that the plants occupy. This is typically done by harvesting the leaves, measuring their area using a leaf area meter, and then dividing that total area by the area of the plot where the pak choi was grown. Alternatively, LAI can be estimated using indirect methods, such as using light interception techniques or photographic methods to capture leaf cover and calculate the index based on those images.
