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!
length X width area LXW=A
From the known length of the sides, length and width, to find the area you multiply(times) the length X width = Area. If you have a given area and wish to find the total area of an adjacent (next to) area, you add the areas. Area(1) + area(2) = Area (Total(.
Total surface area = (2*pi*radius2)+(diameter*pi*height)
A =Lw....A- areal - lengthw - width
Total surface area = (2*pi*r2)+(pi*r2) Area = 300*pi in square units
Find the total land area of Belarus.
Find the area of each face separately and then add them together for the total surface area.
first find the area of the base. then multiply it by the height and divide it by three.
length X width area LXW=A
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.
From the known length of the sides, length and width, to find the area you multiply(times) the length X width = Area. If you have a given area and wish to find the total area of an adjacent (next to) area, you add the areas. Area(1) + area(2) = Area (Total(.
To find the area of the shaded part in a rectangle, you first find the total area of the rectangle by multiplying its length by its width. Then, you subtract the area of the non-shaded part from the total area to get the area of the shaded part. The formula would be: Area of shaded part = Total area of rectangle - Area of non-shaded part
Total surface area = (2*pi*radius2)+(diameter*pi*height)
whats the object
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).
The surface area of a space figure is the total area of all the faces of the figure
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.
