Here's what you do... take a graph paper.. the 1mm x 1mm graduated. trace the leaf on the graph paper. remove the leaf. then count the whole squares occupied by the leaf. write down the number. count the half 3/4th filled squares and write the number down. count the number of half filled squares and divide the number by two and write it down. leave out 1/4th filled squares. add the numbers you have written down. the number you get is the surface area of one side of leaf. doubling it will give you the surface area of the entire leaf in sq cm

What is the instrument used in a sumberine to see above the surface of water?
A periscope is the instrument used in a submarine to see above the surface of water. It works by using mirrors to reflect light down into the submarine while allowing for observation of the surface without exposing the submarine itself.
What is the instrument that measures changes in air pressure without using a liquid?
An aneroid barometer is an instrument that measures changes in air pressure without using a liquid. It uses a flexible metal box called an aneroid cell that expands and contracts with changes in pressure, which is then translated into a measurement on a dial.
What Instrument measures A wind vane?
An anemometer is the instrument that measures wind direction using a wind vane.
Can you play wind instruments without a tongue?
Yes, some wind instruments can be played without using your tongue by using alternative techniques such as breath control, embouchure adjustments, and manipulating air flow within the instrument. However, the tongue is commonly used to articulate notes and create different sounds on wind instruments.
How can an observer tell that Mar's northern hemisphere surface is younger than its southern hemisphere surface without using radioisotope dating?
Without Radioisotope dating it is very difficult to determine the age of a surface exactly. One way to estimate the age of the surface is looking at the number of impact craters. Assuming meteorites hit at regular intervals, the surface with more impact craters is the oldest.

How can one determine latitude and longitude without using GPS technology?
Latitude and longitude can be determined without using GPS technology by using tools such as a sextant, astrolabe, or a compass. By measuring the angle of the sun or stars above the horizon, sailors and navigators can calculate their position on the Earth's surface. Additionally, landmarks, maps, and celestial navigation techniques can also be used to determine latitude and longitude.
What direction can be measured using what instrument?
Direction can be measured using a compass, which points towards the Earth's magnetic poles. This instrument uses the Earth's magnetic field to determine north, south, east, and west directions.
How do you determine the volume of sugar without using water displacement?

Can an aircraft land at an airport using an instrument or precision approach without approach lights?
yes
How can screw hooks be installed without using a drill?
Screw hooks can be installed without using a drill by using a screwdriver and manually twisting them into the desired surface.
An electric charge can be detected by an instrument called?
An electric charge can be detected by an instrument called an electroscope. It works by using the principles of electrostatics to determine the presence and type of charge on an object.
How can one determine temperature without using a thermometer?
One can determine temperature without using a thermometer by observing physical changes in materials, such as the melting point of ice or the boiling point of water, or by using the sense of touch to feel the warmth or coolness of an object.
How can you determine the direction on a map without a compass rose?
You can determine the direction on a map without a compass rose by using cardinal direction.
