Given:
Tina cut 3 wood boards each into 4 equal pieces.
She used 3 of the pieces for a craft.
Question asked:
What fraction of the boards does she have left ?
Write this fraction as a mixed number.
Solution:
<em><u>As she cuts 3 wood board each into 4 equal pieces :-</u></em>
Total number of equal pieces = 
Pieces of wood used = 3
Remaining pieces = 12 - 3 = 9
<h3>
<u><em>Now, we will write these 9 pieces in terms of number of wood boards</em></u>.</h3>
<u>By unitary method:</u>
4 pieces constitute = 1 wood board
1 piece constitute = 
9 pieces constitute = 
<em>Now, convert it into mixed fraction:</em>

Therefore, fraction of the boards she have left is
.
Answer:
it is wonderful short-story reading experience./ a collection of short stories.
You problem is you don't have any problem. You have a bunch of formulas for the perimeter and area of some shapes.
As for using the formulas, usually you're given all but one of the variables and you can solve for the remaining one.
Notice how the triangle result doesn't have area as a function of a, b and c. That's called Heron's formula and is usually not taught to secondary school students. I don't like to teach it either because Archimedes' Theorem is so much better:
The sides a,b,c and area S of a triangle satisfy
