How to solve grade eight formulas?
To solve the above formulas let's take some examples.Go through these problems and analyse them to understand how they are used.
- Example: Find the area of a rectangle whose length is 10 c.m and width is 4 c.m?
Let's solve this.
Solution: Data : length=l= 10 c.m
width =w= 4 c.m
We know that formula for area of rectangle is A= lw
A= 10*4
A= 40 c.m
So our answer is forty centimeters.
2.Example: Find out the area of a circle whose radius is 7 c.m?
Let's try to solve this problems.
Solution: Data: radius = r = 7 c.m
Pi= π =22/7
You know that formula of Area of circle is A= π r ²
A = (7) ² x 22/7
A = 49 x 22/7
A = 7 x 22
A = 154
Hence the area of circle is 154 c.m.
