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
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.
One common indicator of leaf area in pechay (Chinese cabbage) is the measurement of leaf length and width using a ruler or measuring tape. By multiplying these two measurements together, you can calculate the leaf area. Another method is using specialized tools like a leaf area meter, which provides a more accurate measurement of the total leaf area.

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.
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.

length x width = area
Leaf surface area is important to measure in plant studies because it provides a quantitative measurement of the leaf's overall size and potential for photosynthesis. Understanding the surface area helps researchers analyze how efficiently plants can exchange gases with their environment, absorb light for photosynthesis, and regulate transpiration. Additionally, leaf surface area data can be used to compare different plant species, assess the impact of environmental factors, and evaluate the overall health and growth of plants.
Calculate the area of the room. Calculate the area of the window (or whatever opening) Room Area*100/Window Area
I am afraid there is no 'formula' for finding the area of a leaf, since leaves are so variable in shape.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 MeterMy 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 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
