Question

(05.01)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.

Answer 1

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.
