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

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 formula for finding the area of a leaf?
There is no specific formula for finding the area of a leaf as the shape of leaves can vary widely. One common way to estimate the leaf area is by using a grid method, where the leaf is placed on a grid paper and the number of full squares covered by the leaf is counted. This count can then be used to calculate an approximate area. Alternatively, there are specialized instruments called leaf area meters that can measure the leaf area directly.
What is the unit of leaf area index?
m2/m2
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)
How do you find the area of a leaf?
You times the long stem by the short stem
How do you calculate surface area?
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

How do you calculate leaf area duration LAD?
LAD= [(LAI1 + LAI2)/2] x Number of days LAI is Leaf Area Index. That number is usually given, if not it can be found by Leaf Surface Area/Soil Surface Area.
How many stomata in a banana leaf?
more than a desert plant as the humidity and temperature allows for this
Indicator of leaf area of pechay?
The best method to measure the area of a leaf 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
What is the molecular formula of aloe barbadensis leaf juice?
Aloe barbadensis leaf juice is mostly water, but has over 75 different nutrients in it. Each compound of this complex mixture has a specific chemical formula.
Why calculate leaf surface area with transpiration?
The stomata on the underside of the leaf regulate transpiration. The leaf surface area helps to estimate the number of stomata, which could speed up or slow the rate of transpiration.
What is the largest area of the leaf?
The mesophyll- the middle.
What leaf area does photosynthesis happen?
It is about green plants. It is happening in every single leaf alive.
What parts of a leaf aid in photosynthesis?
green area
What is the unit of leaf area index?
m2/m2
