Sammy is trying to determine how many triangles she can create out of a square grid that has a side of 14 inches. Use the image
below to determine the area of the triangle and how many she can cut out. The area of the triangle is 49 in2, so she can create only 2 triangles.
The area of the triangle is 49 in2, so she can create only 4 triangles.
The area of the triangle is 98 in2, so she can create only 2 triangles.
The area of the triangle is 98 in2, so she can create only 4 triangles
To find the area of the triangle, you use the formula A=bh/2. This gives you the area of 49in^2 for the triangle, eliminating choices C and D. The area of the entire square is 14^2, or 196in^2, which gives us 4 when divided by the area of the triangle, 49in^2. Therefore, the answer is B, or that the area of the triangle is 49in^2 so she can create only 4 triangles.
There were 11 crackers to begin with. Because if you give the fractions a common denominator of 12 you multiply how you got to 12 by the top as well then you would subtract and add it to the five that were left
