Well if you just have a rectangle or a square, that's easy. Just times the length by the width. For example:
Length = 5cm
Width = 6cm
Area = 20cm squared
When you write the area, put a little '2' by the measurement to show 'squared'.
However, if you have an irregular shape, split it into small rectangles then use the steps above on each rectangle to find the area. Then add them all together - remembering the little 2 to show that it's squared.
For triangles, just use the ordinary rectangle steps, then half the answer. This is because if you put a triangle on that was the same size, it would be a rectangle (sorry, I'm not too good at explaining).
If you have other shapes - ask someone else. I'm not really sure for that.
Now, next lesson, how to do long multiplication!
Just kidding, don't worry!
Sorry it's so long and boring!

Find the total surface area of this half sphere with a radius of 10?
Total surface area = (2*pi*r2)+(pi*r2) Area = 300*pi in square units
How do you find the Geometric Probability of something?
it is actually very easy what you do is find the area of both shapes then if your problem is like find the chances of hitting the shaded area you do area of shaded divided by the total area of the whole object then multiply that by 100

How do you calculate the total surface area of prism?
Find the area of each face separately and then add them together for the total surface area.
How do i find the total area of pyramid?
first find the area of the base. then multiply it by the height and divide it by three.
How do you find the total area of the wall?

How do find the area of a shaded region if you have the total area of 201 but you only need to find 60 degrees?
TOTAL AREA=201, REQUIRED AREA=201/6=33.3. As 60 degrees covers only 60% or one sixth of a circle, to calculate required area, divide the total area by 6.
How do you find the total surface area of a closed cylinder?
Total surface area = (2*pi*radius2)+(diameter*pi*height)
Find the total surface area of this object?
whats the object
How do you find lateral area of a cylinder?
To find the lateral area of a cylinder, multiply the circumference (πd) by the height (πdh). After you have this, you can find the total surface area by adding twice the area of the base (2πr2).(Lateral area = πdh), (Surface area = πdh + 2πr2).
How do you find the surface area of a space figure?
The surface area of a space figure is the total area of all the faces of the figure
How can finding area of a rectangle help you find the area of other shapes?
By finding the total area, you can see if all of the areas of your shapes combined match the total area of the rectangle. It's a safe-check.
How do you find the total area of a room?
A =Lw....A- areal - lengthw - width
Find the total surface area of this half sphere with a radius of 10?
