What is the area?
The area of the foam indicates how much space is needed on a flat surface. Remember how much paper you need to cover completely.
Rectangular region
A rectangle has two long sides (length) and two short sides (width).
Formula:
Example area:
If you have a rectangle:
length = 8 cm
width = 4 cm
Area= 32 cm²
Triangular
Triangular
To find its area, you need the foundation and height (size from the base).
Parallels look like diagonal rectangles.
The opposite page is the same and parallel. 60cm²
The diamond shape is the same for every four pages and looks like a diamond form. We find his area on two diagonals (the lines passing). 6 = 24cm²
A trapezoid has several parallel sides called the foundation and the base.
The distance between them is height. ½12.4= 24cm²
Find its area using the radius (R) or diameter.
The radius is the distance from the center to the edge. 7= 153.86cm²
is half a circle. Cm
then
3.144= 25.12cm²
base base base
rhombus rhombus×bro> trapezium
trapeziul = 3.14）
½C The rectangular length is 12 cm and width is 5 cm.
What is the area?
Q3. Find the area of the base of 10 cm and the triangle with a height of 3 cm.
Q4. What is the height of the area of a circle with a radius of 6 cm?
Swing base = 8 cm, base = 6 cm, height = 5 cm.
Find that area.
Answer:
9 * 9 = 81cm²
12.12 = 60cm²
½ 3 = 15cm²
3.14 = 113.1²
½(8 + 6) 5 =½145 = 35cm²
Final Thoughts
Area is about how much space there is on a flat surface.
If you know the formula, it’s very easy to calculate the regions of different shapes!
